Whereis lilylib etc. - Build system - Python modules

[Villum Sejersen]

Hello
For several years I have been compiling the lilypond master branch.
Today’s result is strange: LilyPond compiles and installs as it should, 
but all the python modules throw an error when called.

The error shown below on loading modules also was present for a few days 
during the 2.13 development series, but apparently accidentally solved 
without being recognized as a bug.
