You created the secret key with gpg and copied it over to PGP I
assume.  GPG creates preferences to the Twofish algorithm and
therefore it tries to use Twofish and the new MDC encryption packet
which PGP 6.5.8 does not understand.  

2 solutions:

  1. Update to PGP 7.0
 
or

  2. Use  "gpg --disable-cipher twofish"  ( you may want to put it
     into ~/.gnupg/options.

MDC packets are needed to avoid a (not so) new choosen ciphertext attack,
therefore it is a good idea to use the first solution.

Ciao,
