thanks, i've just fixed these, but they were harmless.

since the backtrace doesn't contain any game code but just a recursion of 
gs_objc_proxy_lookup() and objc_msg_lookup() i'm not sure what the cause of 
this could be or even how to start debugging it.

i just did another fresh checkout on linux and verified that the project builds 
*and runs* fine.

i'm actually not so sure what dependencies you are talking about
• the thing most complicated to install is gnustep/clang/libobjc but since you 
are on a gnustep list i believe you already had those installed....
• most other dependencies are included in source form and don't need any 
installation (snappy, freetype-gl, cml, ...)
• the remaining dependencies are SDL, SDL_mixer, bullet, alut & libavcodec. 
most of them are already included as linux 32&64 .so files for convenience and 
even if you are on BSD installing these via the ports tree should be a matter 
of seconds?

once we figure out what actually took you so long i'll be happy to update the 
readme to make things easier in the future ;)
