Every preference list contains Triple-DES, whether you explicitly list it there or not, and every OpenPGP program is compatible with Triple-DES.  If no other compatible ciphers are found, the answer is Triple-DES.

Patch the source :)

There is no way other than that.  3DES is a required part of OpenPGP, so if you remove it, you're not going to play well with the other programs out there.
