Just attempting to fill in missing detail: PGP first used for its
symmetric cipher Zimmerman's own amateur effort "Bass-o-Matic", which
was quickly dropped and replaced with the IDEA algorithm. IDEA is
patent encumbered (and will remain that way for some years, yet).
GnuPG lacks IDEA support. It was included for a while as an optional
module, but has bene removed from the tarball. (You can find it and
retrofit it, if you search a bit.)
The problems with dodgy RSA support have, as you mentioned, now gone
away: One can achieve maximum compatibility with various PGP versions
by avoiding mixing RSA and Diffie-Hellman / DSS, as detailed here:
That and the lingering IDEA problem (limiting only compatiblity with
some PGP 2.x users) are all I'm aware of. PGPi, unlike GnuPG, _does_
include IDEA code by default.
