Considering that MD5 takes an arbitrary string with an arbitrary length and maps that to a 128 bit string, it's certainly not collision free.

Having said that, your question lacks anything Perl specific. You've more chance of getting a useful answer in a more appropriate forum - md5 isn't language specific.
