commit: http://git.buildroot.net/buildroot/commit/?id=9722381c0da7203c725c8f589cd84b4c55f8c9a7
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Currently the graph-build-time script prints a python exception if a
needed module cannot be imported. Catch the exception and tell the user
which packages are missing, as we do for other missing dependencies.
