The normal way looks like this:
perl Makefile.PL
make
make test
make install
For details see
perldoc perlmodinstall
perldoc ExtUtils::MakeMaker
If you don't have a 'make' command on your system, just copy
the 'MD5.pm' file to a directory named 'Digest/Perl/',
e.g. /home/lackas/usr/perl/Digest/Perl/MD5.pm
and insert that directory to Perl's search path with a
'use lib' statement:
use lib '/home/lackas/usr/perl/';
use Digest::Perl::MD5
That's all.
Have fun,
