The best reference known to me for doing things like this is the Curl
library with its zillions of linking & license options.  They somehow
manage to pull it off, so it's certainly possible.

Sadly, it's in the planning stage and involves a full rewrite of the
entire library... not going to happen soon :S
(The logic is the other way around, there's some consideration about
redoing the zebra protocol, and the library with it, and with that LGPL
is an option.  The existing code cannot reasonably be relicensed...)
