Hi,
Now that I have a computer w/ the new OSX (10.11)  I'm going to try to fix
the [gemvertexbuffer] issues some folks were having that I wasn't
experiencing on OSX 10.6.
However, I'm getting these errors while building the latest Gem:
clang: warning: optimization flag '-falign-loops' is not supported
clang: warning: optimization flag '-falign-functions' is not supported
clang: warning: optimization flag '-falign-jumps' is not supported
clang: warning: argument unused during compilation: '-falign-loops'
clang: warning: argument unused during compilation: '-falign-functions'
clang: warning: argument unused during compilation: '-falign-jumps'
... And then fatal messages below.  I tried reinstalling QT but no luck.
