problem with newbies key attached sig

[Carl William Spitzer IV]

pg: using secondary key 8D794F7D instead of primary key 33A3AB45
gpg: 8D794F7D: There is no indication that this key really belongs to
the owner
gpg: [stdin]: encryption failed: unusable public key

he is using pgp653 under winME.  I am using gnupg124 under gnome 

next it will be kgpg and inline sig attempt
