Upgrade to 0.4.4, the current release... that will fix a number of
problems with PGP5 compatibility.

Sorta.  ElGamal is a modification to DH.  It's the same concept (the
underlying reason for why it's hard to break is the same).  DSA is the
algorithm, DSS is the standard.  The difference between the two is
pedantic.

You should upgrade to 0.4.4 for good measure, but it should be trivial
even on 0.4.0 to import the key.

Try:   pgpk -x 0x12345678 | gpg --import

What error message do you get?
