this issue probably shows up now just because now on every "scons
option=value" invocaton, the configure step is automatically
called (which, btw, i a *very* convenient change).

i tried this here and got the same error. looking at config.log
file i saw that xercesc check was the first one using g++ 
(instead of gcc) and, thus, was using "distcc g++". the error was
simple: could not found "distcc". then i installed distcc and all
configure went fine. so, hernan, check if this is also your case.

so now the TODO is: adding a custom distcc checking. i've filled
a bug for that (#262). patches are welcomed!
