A quick CPAN search turns up Digest::Perl::MD5: 
NAME
    Digest::MD5::Perl - Perl implementation of Ron Rivests MD5
    Algorithm

DISCLAIMER
    This is not an interface (like `Digest::MD5') but a Perl
    implementation of MD5. It is written in perl only and because of
    this it is slow but it works without C-Code.

Hope this helps :-)
