Well, on SPARC, the Sun compilers are better than gcc, so there really is an 
advantage to getting this sorted out.

I do not know SCons myself, but I do know that in the Sage project, SCons has 
caused many issues. Whether it is a fault of SCons, or the way people write the 
code for SCons, I do not know.

I know recently someone changed a package that was using SCons, and stripped it 
all out. There is some code I need to fix, and I will take the same course of 
action. It seems more trouble than it is worth to me.
