To install a local perl module, follow steps like these:

<code>
mkdir ~/lib
cd ~/lib
wget http://search.cpan.org/CPAN/authors/id/R/RK/RKHILL/DateTime-Astro-Sunrise-0.01_01.tar.gz
tar -zxvf DateTime-Astro-Sunrise-0.01_01.tar.gz
cd DateTime-Astro-Sunrise-0.01_01
perl Makefile.PL PREFIX=~/lib LIB=~/lib
make
make test
make install
<code>

In the actual script you want to run, include this:
<code>
use lib '/path/to/username/lib';
use DateTime;
use DateTime::Astro::Sunrise;
</code>

Simple test script that checks the perl modules used on local system:

  #!/usr/bin/perl -w
