use lib '.';

[Rick Measham]

Its not redundant as Martins output proves. Perl looks through @INC 
for its modules. If I have my home-rolled Carp.pm in my local 
directory then it wont be found unless I use '.';

Here it finds the one in site_perl (or wherever it happens to be)
>[107]mryan at host:~> perl -e 'print join("\n", @INC), "\n"'
>/usr/libdata/perl/5.00503/mach
>/usr/libdata/perl/5.00503
>/usr/local/lib/perl5/site_perl/5.005/i386-freebsd
>/usr/local/lib/perl5/site_perl/5.005
>.


Here it will find the one in the local directory.
>[108]mryan at host:~> perl -e 'use lib "."; print join("\n", @INC), "\n"'
>.
>/usr/libdata/perl/5.00503/mach
>/usr/libdata/perl/5.00503
>/usr/local/lib/perl5/site_perl/5.005/i386-freebsd
>/usr/local/lib/perl5/site_perl/5.005
>.
