These are good objections, but I don't know how well they apply in the
GPG case. Judging by the ChangeLogs, GPG (at least 1.4.x) does not
have that many authors. Even that doesn't matter because if the goal
is to allow linking with sub-dependencies of OpenLDAP and libcurl,
we're only talking about the contents of the keyserver directory. In
the keyserver directory, you really only need permission from one
author, and I would give it.
How about a license exception (or just LGPL) for gpgkeys_ldap,
gpgkeys_curl, and gpgkeys_hkp? They're separate programs that
communicate via pipes (the classic example of the barrier that the GPL
does not cross). Their licensing need not be the same as the gpg

At least for GPG, I suspect most people won't care (or even notice)
whether it is OpenSSL or something else. They just want to be able to
build the software and use keyservers. If that happens through
OpenSSL, great. If that happens through GnuTLS, also great.
