Subject: Re: IPB2 and syntax - same question but still confuse

Isn't the problem simply that W.A's 64-bit build does not *have* 
md5_gen(12) ? I'm not sure exactly when it gets enabled or disabled, but 
on my linux-x86-64 it's not:

$ ./john -test -fo:md5_gen\(12\)
Unknown ciphertext format name requested
