It just worked for me when I tried.  I used --default-key to select my
RSA key and used --edit-key to select my new key and typed "sign".

Sure.  I just used --clearsign to sign a file with my RSA key and pgp2
recognized it.

I see that if I use --sign and then use pgp2 to try to verify the ".gpg"
file, pgp2 can pull out the plain text but it doesn't say anything about
the signature.  I think that used to work...  I recall that --rfc1991 was
supposed to make things more compatible, but that doesn't seem to make any
difference, and neither does --armor.
