gmake parallel makefiles should work.  However, it is possible to create 
a project that will not work for various reasons.  These reasons involve 
custom commands that generate the same files from different targets.  In 
that case it is too much parallel building.  I am not aware of gmake not 
working in parallel at all on any system.  Sounds more like a gmake 
install problem.
