hmm... im getting to the step where i have to run 'qmake' in .../libbitdht/src/ directory, but i'm not able to open a compilable file in xcode... when i'm trying to open the bitdht.pbproj container, xcode 4 says:
Failed to load project at '/Users/xyz/bin/retroshare/trunk/libbitdht/src/bitdht.pbproj', incompatible project version.
