It depends really on what OS you are now - I assume as with Linux, most
other
Perl installs will include some fundamental basic modules like DBI (for
databases ) and CGI ( optional, but usefull ).

TIP: If I want to do something, I go to http://search.cpan.org/ and search
for
a keyword that summrises my problem - 9/10 times a module pop's up. I then
enter the command:

 $ perl -e 'use The::Module'

and then I see if I have it, and if it works. It will work if the command
returns no output and gives you a shell promt again.

Sample: I want to convert between various mathematical Units. In CPAN, I did
a
search for 'unit convert' (
http://search.cpan.org/search?m=all&q=unit+convert&s=11 ) and found a Module
called Math::Units (
http://search.cpan.org/author/KENFOX/Math-Units-1.2/Units.pm ) - and as you
can see, does basically what I want. the shell test:

<OUTPUT>
$ perl -e 'use Math::Units'
Can't locate Math/Units.pm in @INC (@INC contains:
/usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl
/usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi
/usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl .) at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
</OUTPUT>

So, now I have to install it.

Cheers
