First Posting,
Sadly it is because I need help with my issue. Unva crashes when I attempt to join the training/developmental servers. Giving the recursive ABI mismatch after ABI mismatch error.
When my first attempt to run the Mac installer was not successful, I deleted all the old .pk3 files and ran the installer again. I have verified the new files with the md5sum as outlined in the Unva/wiki pages. I have also attempted to pass simpler +set for the graphics. However, my situation persists. From my crashlog.txt, I believe my issue lies in the OpenGL engine (last lines) - but I am unsure.
However, I just noticed that the top of my crashlog says 0.14 (not 15) - so did I need to recompile my application program or something as equally simple? I am a new player and I have started to really enjoy your project - thank you for any help/advice offered. 
Newbie-ly yours,
One (Leif)
