That won't work. With some work you can import the key if it's an v3 RSA key
not larger than 2048 bits (don't use idea for key encryption then or you
won't be able to import the secret key). I don't know if pgp 8.1 creates v3
RSA keys, pgp 2.x can't import v4 keys. GnuPG can't create them without a
patch (so without a recompile).

However, the messages encrypted with pgp 2.6.3i to such a key will still use
the IDEA symmetric algorithm.

If you want to communicate with users of unpatched pgp 2.x versions, you'll
really need to get IDEA integrated in GnuPG. On win32 a dll is sufficient,
but I don't know if the dynamic loading of algorithms works on VMS. If it
does, compiling the module and adding a line in gpg.conf will suffice.
Otherwise, you'll have to recompile.
