That's correct.

This isn't.

Example:

First, install a random module into a non-default location:

/tmp> tar xzf /archive/distfiles/IMDB-Film-0.52.tar.gz
/tmp> cd IMDB-Film-0.52
/tmp/IMDB-Film-0.52> perl Makefile.PL PREFIX=/home/wiz/test

Now try using it:
/tmp/IMDB-Film-0.52> PERL5LIB=/home/wiz/test/lib/perl5/site_perl perl -e 'use 
IMDB::Film;'
Can't locate IMDB/Film.pm in @INC (@INC contains: 
/home/wiz/test/lib/perl5/site_perl

.) at -e line 1.
BEGIN failed--compilation aborted at -e line 1.

But if I rename the directory to match the perl version, it does:
/tmp/IMDB-Film-0.52> mv ~/test/lib/perl5/site_perl/5.16.0 
~/test/lib/perl5/site_perl/5.16.1
/tmp/IMDB-Film-0.52> PERL5LIB=/home/wiz/test/lib/perl5/site_perl perl -e 'use 
IMDB::Film;'  
/tmp/IMDB-Film-0.52>

This is what I want fixed.
