Problem verifying GPG signatures with PGP

I'd like to use the Win 98 build of GPG in a digital signature application,
and I'd like the digital signatures to be verifiable using either GPG or
PGP. So far, I've been able to import and export my public key from GPG to
PGP version 6.5.3. I've also been able to use GPG to verify signatures
generated with PGP. But I can't seem to use PGP to verify signatures
generated with GPG.
Below my "signature" is a test message signed with both programs and the
result when I attempt verification with both programs. At the very end of
this message are the PGP and GPG public keys, respectively, I used to
generate the signatures.
If anyone could play around with this and let me know what's going on, I'd
appreciate it. GPG seems like a great little program and a great
alternative to the increasingly commercialized PGP, and I'd like to be able
to use it.
I don't subscribe to this list, so please copy me on any replies. Thanks!

Could not find a valid trust path to the key. Let's see whether we
can assign some missing owner trust values.
No path leading to one of our keys found.
