Well, LablGTK is not the only package depending on camlp4.
But I agree that the dependency is hardly essential, and could be avoided easily.
For (2) processing in advance is indeed the answer.
For (1) I would rather suggest to do it in the configure script:
we could add a gtk_config.ml, containing interesting results of the configuration.
