 Oh.. and pgp5 is recognizing only the DSA part of the "(1) DSA and ElGamal
(default)" key... I guess...

 It has a POSIX API and a C compiler. But it probably won't be trivial.
Specially when gpg seems to be more Linux centric than other free software
utilities. It will surely become more portable in the future.

 Oh.. BTW, I tried to compile it in Solaris. It failed trying to lock the
memory because it was getting it with malloc (not with mmap, I think there's
not MAP_ANONYMOUS there) and it wasn't page aligned. The problem is fixed
changing malloc for valloc. I don't have the sources here to send a patch.
