That means that you don't have to know the intricacies of configuring CPAN.pm or CPANPLUS to do so. Further, the incantation for a .bashrc file sets all the environment variables necessary. In your example, you're not getting an architecture specific directory in PERL5LIB. Here's an example of what local::lib will do using my "cleanroom" user: <blockquote>$ perl -I$HOME/perl5/lib/perl5 -Mlocal::lib export MODULEBUILDRC="/home/cleanroom/perl5/.modulebuildrc" export PERL_MM_OPT="INSTALL_BASE=/home/cleanroom/perl5" export PERL5LIB="/home/cleanroom/perl5/lib/perl5:/home/cleanroom/perl5/lib/perl5/x86_64-linux-gnu-thread-multi:$PERL5LIB" export PATH="/home/cleanroom/perl5/bin:$PATH" </blockquote> Hope that helps clarify. -- David local::lib sets ExtUtils::MakeMaker and Module::Build to install both Perl modules and programs to a specific directory.

Phillip I was looking at local::lib a few weeks ago and couldn't quite figure out the advantage to using it over something like this in .bash_profile:


if [ -d $HOME/lib/perl5 ]; then
PERL5LIB=${PERL5LIB:+$PERL5LIB:}$HOME/lib/perl5
fi
export PERL5LIB

I'd really like to have a better understanding of when and why to use local::lib and wonder if there are some good examples that folks have to share?
