What does "Exit code: 11" mean when building CMake?

[Ken Cunningham]

cmake (and other software) is quite broken on 10.5 ppc with libgcc7. 

please see the cmake ticket.

rolling back to libgcc7 is presenly the only known fix. there is a pr referenced in the ticket where I reluctantly propose to do that if no better solution is found.

upstream says it's complicated to fix. they have to separate libstdc++ from the libstdc++abi code. Not for the squeamish. Probably few around who could do it.

btw, on macports, you cannot force a compiler like that.
