Here is a log of the error message from the build:

I am using the Mesa 3D Graphics Library release 6.5 from :
http://mesa3d.sourceforge.net/

I have changed a few things in my glibc build procedure (which supplies 
initspin.h), so I'm going to try again and see if this error still 
occurs when I do the Mesa build.
