Owner trust doesn't mean "I trust this person" or "I trust that this
key belongs to the person it seems to". It actually means "I trust
this key to sign other keys". If you want to make a key valid, you
need to either sign it yourself (you can use 'lsign' if you want to
make a local signature that is for your own use, or 'sign' if you want
to make the signature publically for anyone to use). Once a key is
valid, then its owner trust is taken into account with making keys
that it signed also valid.

You were on the right track before. Just instead of giving full owner
trust to some of the developers, lsign their keys also.
