Created attachment 501556 [details] build log My system uses python3. dev-db/mongodb-3.4.9 fails to build since its scons files are all Python2. Applying 2to3 doesn't suffice since it uses modules (like md5) which are not available under Python3 How can I force that Python2 is used (only) while dev-db/mongodb-3.4.9 is built? emerge --info is attached (it's too long to paste here)

Comment on attachment 501558 [details] emerge.info.xz Why would you compress a couple of kilobytes like that?
This means you only have Python 3 on your system? Because even when I set the active Python slot to 3, scons uses Python 2 on my system: # python -V Python 3.4.6 # scons -j4 CC=x86_64-pc-linux-gnu-gcc CXX=x86_64-pc-linux-gnu-g++ --disable-warnings-as-errors --use-system-boost --use-system-pcre --use-system-snappy --use-system-stemmer --use-system-yaml --use-system-zlib --ssl core tools scons: Reading SConscript files ... scons version: 2.5.1 python version: 2 7 14 'final' 0

Non-maintainer major version bump = you get to keep the pieces.
I have the same failure here. Even setting python-2.7 as system default doesn't work. It's still the same error.
The problem is scons-3.0.0, downgrading to 2.5.1 solved it.
Ok, that seems a bit more probable. Helmut, do you also have scons-3?
