 From what I am reading about this is its related to libgl. But on the 
machine I borrowed I used nouveau driver's which uses the libgl that is 
expected not the nvidia's supplied version. So maybe that is not fully 
it. But still all seems related to being in an X environment for me when 
building. Which is at least easy to work around.

Will post if it segfaults again on either machine once they are done.
