I think you need a debugging perl for the environment var to work. [...] you can get the same effect from Hash::Util::hash_seed()

Both environment variables shown in the OP seem to be working:

$ PERL_HASH_SEED_DEBUG=1 perl -MHash::Util=hash_seed -le'print hash_se
+ed'
HASH_SEED = 165032588
165032588
$ PERL_HASH_SEED_DEBUG=1 perl -MHash::Util=hash_seed -le'print hash_se
+ed'
HASH_SEED = 725441538
725441538

tye's getKeyCollisions shows always the same output here:

$ PERL_HASH_SEED_DEBUG=1 perl gkc.pl | md5sum
HASH_SEED = 501557310
e4d6401f730eede592733482fac0ec61  -
$ PERL_HASH_SEED_DEBUG=1 perl gkc.pl | md5sum
HASH_SEED = 1324598606
e4d6401f730eede592733482fac0ec61  -

I don't know if it's supposed to do so or not. I'm beginning to take a fancy to this :) since it seems to be impossible to obtain some different output of anything between runs of perl (well, anything except hash seeds!).

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
