PGP probably doesn't support the gpg's default symmetric encryption
algorithm (BLOWFISH). Quoting the man page
Use name as the cipher algorithm used to pro=AD
tect secret keys. The default cipher is
BLOWFISH. This cipher is also used for conven=AD
tional encryption if --cipher-algo is not given.
So just tell gpg to do symmetric encryption using one of the algorithms
supported by pgp 6.??. Eg.
$ gpg -a -c --cipher-algo=3Dcast5 > message.txt
