Very often, this error:

> gpg: [don't know]: invalid packet (ctb=2d)

means that the file is corrupt.  A common way of corrupting files is
to FTP them in ASCII mode instead of BINARY.  How are your files being
moved around?

I understand that you successfully read this file with PGP, but which
copy did you test with?  The same one on the same box as GnuPG?
