I hate stuff like this, but such is life.

seems like we could use main['CXXVERSION'] instead of doing the readCommand.

Sorry I didn't read the comment more closely.  What exactly is happening with CCVERSION?  You're saying that if we do something like "CC=gcc-4.1" on the command line that CCVERSION doesn't get the right answer?  That just totally sucks.  SCons has problems.
  1. that is exactly what i'm saying... it's a known bug but apparently the right fix is quite a mess.
