Comment (by thoughtpolice):

 Ugh, so this is a slightly annoying 'fix' because the compilation options
 are hashed as part of the recompilation check, and simply loading the
 dynamic interface file won't work as the hashes will differ (because
 -dynamic-too implies some other options). I've almost got a working fix
 for this I think, but it's unclear to me how hacky it might be.
