We ran scons on Mac OS X where g++ was not installed. Instead of an error message stating that the default compiler could not be found, scons set env['CXX'] to None and tried to compile, which resulted in obscure behavior that was a little difficult to track down.

https://scons.org/wiki/BetterErrorMessages is a description of how this situation should be handled. At the time this comment is posted, it's an early draft, and comments and questions from those who have encountered the situation would be appreciated.

I just saw this happen on a virgin Ubuntu 9.04 Desktop install -- the g++ package is not installed out of the box, and scons tries to compile with CXX being None...

Seems like at least those builders listed in GlobalDefaultBuilders could have some sort of error handling defined for them. That list is only used for populating DefaultEnvironment at the moment and uses the DefaultEnvironmentCall class, but one could use a similar mechanism for a regular env, I presume?
