>> Thanks, Robert, that worked very well. I have one more question, if I may. So I'm embedding Mono on Android on ARM. Up until now, I've been AOT compiling the libraries by running a little app on the Android device itself. Obviously, in the long term, this is not really a good option. So now, I'm trying to build a Mono cross compiler for Android ARM on my Mac OS X machine (gcc --arch returns "i686-apple-darwin11-llvm-gcc-4.2" if that is useful).
