That is correct. PGP 5 deprecated RSA keys in favor of Diffie-Hellman (DH)
keys, and PGP 6 does not grok RSA at all. RSA is patented, and has an
extremely restrictive use license, whereas the DH patent has expired and is
now public domain. Likewise, PGP 5 deprecates IDEA in favor of 3DES.
GnuPG, being free software, cannot use RSA or IDEA because of patent and
license restrictions. So it is probably time for you to bite the bullet
and generate a DH key for yourself.
 There are RSA and IDEA modules for GnuPG, but the former cannot be used
in the US, and neither are free which is why they are not distributed with
