Import help

[r cannon]

Hey there
Newbie question

Trying to import someones pubkey. Using mac os x have tried the GPG Keys
gui, which said it sucessfully imported the pubkey.txt file (however the
file never showed up in the list).

Have also tried gpg --import ~/path/pubkey.txt but this comes back with the
error 
'gpg: NOTE: old default options file `/Users/rebecca/.gnupg/options' ignored
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0'

Checking --list-keys after either method brings only my key....

The .txt file has a proper looking key in it -

-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: GnuPG v1.2.4 (GNU/Linux)

(where this is a long string of randomness)

-----END PGP PUBLIC KEY BLOCK-----

Any advice would be most appreciated.
