If I remember correctly, this error message is a bug that was fixed  
sometime after 1.2.4.  The error message should be "no ultimately  
trusted key found"  The particular key ID given is not correct.

The error just means that you don't have an ultimately trusted key,  
and so cannot generate a trust database.  I expect the key you just  
imported is the one you intend to use, so just make that your  
ultimately trusted key.  On the 1.2.4 side:

  gpg --edit-key (your key id that you just imported)
  trust
   (set the key to "ultimate")
  save

Then you should be able to build your trust database.
