Comment(by snc@…):

 I've tried my patch, which doesn't do it.  Setting the build.env similarly
 has no impact.

 It seems that editing the SConstruct files makes an impact, however it
 results in a failure when I change g++:
 {{{
 EnvironmentError: No tool named 'g++-4.2': not a Zip file:
 EnvironmentError: No tool named '/usr/bin/g++-4.2': not a Zip file:
 }}}

 Any suggestions?
