Trying to emerge mongodb 2.0.7 (and 2.0.6, by the way) fails with an error about the C++ compiler not working: scons -j3 --cxx=x86_64-apple-darwin11-g++ --use-system-all --sharedclient --usev8 all scons: Reading SConscript files ... scons version: 2.2.0 python version: 2 7 3 'final' 0 using system version of: pcre using system version of: sm using system version of: snappy Checking whether the C++ compiler worksno c++ compiler not installed! It seems like this is really a problem with scons not having the correct environment.

I think this is a PATH issue
same problem on Linux
Bug in scons ebuild. Fixed that now. Will have to re-emerge scons. Reducing to Mac OS X problem for MongoDB.
Hey John, could please try the patch in bug 482178 to see if it solves this?
I finally got a chance to test this out and the SCons fix works. I was able to emerge mongo-2.4.6 with scons-2.2.0. However, mongodb still doesn't emerge out of the box on prefix OSX because libunwind refuses to emerge (which is a transitive dependency the google-perftools dependency). I had to update the mongodb ebuild to exclude the google-perftools dependency and remove the --use-system-tcmalloc argument to SCons to get the build to work. Should I file that as a new bug?
I'm sorry but this needs to be revisited.
