Unexpected behavior of "configure" "make" and __osmesa_print__.cc

Configure did not find my osmesa

configure:77609: WARNING: OSMesa library not found.  Offscreen rendering with 
OpenGL will be disabled.

However, “make” still compiles __osmesa_print__.cc

I am able to adjust configure so that osmesa passes, but then compiling 
__osmesa_print__.cc fails.

My guess is that configure isn’t working for osmesa on Mac OSX. Perhaps if that 
can be fixed offscreen rendering will work.

Anyone have any insight here?
