gpg with current pgp keys

looks like the passwd thing is ok.
Maybe the person who encrypted the message used IDEA as symetric key 
algorithm? IDEA is not a free encryption algorithm and that's why it's not 
supported in gnupg by default.
You have 2 options:
- Tell the person who wrote the message to use CAST or 3DES as symetric 
cipher. (Can be switch in PGP preferences)
- Use the gnupg IDEA extensions ( not allowed for commercial use afain )

BTW, is there already a FAQ or HOWTO on implementing this? Would be nice.
