Does anyone fancy having a look at trying to fix this? It probably needs someone with knowledge of SCons, or at least python better than me. Basically, the library is not respecting the variable CXX (nothing unusual), but choses the Sun C++ compiler in preference to the g++ (very unusual), even if the Sun compiler is not in the path, and CXX is set to g++. This is really the only thing that presents Sage from building quite easily on Solaris.
