The GPL should not be used in libraries, even if it's only used . Have
you tried building CLucene, or why do you think it needs GCC4? Even if
it needs GCC4, it should not be a show stopper, as only the indexing
server will link against this library, right?
And the communication with the server is GCC agnostic in any case.

That sounds good to me.
