I've looked at this before and Mono won't load any libraries invoked with p/invoke if they are built with -fobjc-gc-only. However I just looked some more at this and it will load libraries built with -fobjc-gc. Apple's gcc docs say that this requires "additional runtime support which is not present in any released version of Mac OS X", but I think that that is a lie.

I'm a bit swamped at the moment but I will definitely give it a go as soon as I can free up some cycles. When I do I'll use an environment variable so you can build mobj with or without unmanaged GC.
