DESCRIPTION

48       perlbrew is a program to automate the building and installation of perl
49       in the users HOME. At the moment, it installs everything to
50       "~/perl5/perlbrew", and requires you to tweak your PATH by including a
51       bashrc/cshrc file it provides. You then can benefit from not having to
52       run 'sudo' commands to install cpan modules because those are installed
53       inside your HOME too. It's a completely separate perl environment.
54

INSTALLATION

56       To use "perlbrew", it is required to install "curl" or "wget" first.
57       "perlbrew" depends on one of this two external commmands to be there in
58       order to fetch files from the internet.
59
60       The recommended way to install perlbrew is to run this statement in
61       your shell:
62
63           curl -L http://xrl.us/perlbrewinstall | bash
64
65       After that, "perlbrew" installs itself to "~/perl5/perlbrew/bin", and
66       you should follow the instruction on screen to setup your ".bashrc" or
67       ".cshrc" to put it in your PATH.
68
69       The downloaded perlbrew is a self-contained standalone program that
70       embeds all non-core modules it uses. It should be runnable with perl
71       5.8 or later versions of perl.
72
73       This installer also installs a packed version of "patchperl" to
74       "~/perl5/perlbrew/bin", which is required to build old perls.
75
76       The directory "~/perl5/perlbrew" will contain all install perl
77       executables, libraries, documentations, lib, site_libs. If you need to
78       install "perlbrew", and the perls it brews, into somewhere else
79       because, say, your HOME has limited quota, you can do that by setting a
80       "PERLBREW_ROOT" environment variable before running the installer:
81
82           export PERLBREW_ROOT=/opt/perlbrew
83           curl -L http://xrl.us/perlbrewinstall | bash
84
85       By default, "perlbrew" looks for the intialization file that exports
86       "PERLBREW_ROOT" in "~/.perlbrew/init".  In some cases (for instance, if
87       your home directory is shared across multiple machines), you may wish
88       to have several different perlbrew setting per-machine. If so, you can
89       use the "PERLBREW_HOME" environment variable to tell perlbrew where to
90       look for the initialization file.
91
92        # on machine a
93        $ PERLBREW_HOME=~/.perlbrew-a PERLBREW_ROOT=~/perl5/perlbrew-a ./perlbrew install
94
95        # on machine b
96        $ PERLBREW_HOME=~/.perlbrew-b PERLBREW_ROOT=~/perl5/perlbrew-b ./perlbrew install
97
98       If you specify "PERLBREW_HOME", you will also need to specify both
99       "PERLBREW_HOME" and "PERLBREW_ROOT" when you first install perlbrew.
100       After that, you'll need to make sure "PERLBREW_HOME" is exported when
101       you log in, before you source "$PERLBREW_ROOT/etc/bashrc" (or "cshrc").
102       Example ".bashrc":
103
104           if [ "$(hostname)" == "machine-a" ]; then
105               export PERLBREW_HOME=~/.perlbrew-a
106               source ~/perl5/perlbrew-a/etc/bashrc
107           elif [ "$(hostname)" == "machine-b" ]; then
108               export PERLBREW_HOME=~/.perlbrew-b
109               source ~/perl5/perlbrew-b/etc/bashrc
110           fi
111
112       You may also install perlbrew from CPAN:
113
114           cpan App::perlbrew
115
116       However, please make sure not to run this with one of the perls brewed
117       with perlbrew. It's the best to turn perlbrew off before you run that,
118       if you're upgrading.
119
120           perlbrew off
121           cpan App::perlbrew
122
123       You should always use system cpan (like /usr/bin/cpan) to install
124       "App::perlbrew" because then it will be installed under a system PATH
125       like "/usr/bin", which is not affected by perlbrew "switch" or "use"
126       command.
127
128       However, it is still recommended to let "perlbrew" install itself. It's
129       easier, and it works better.
