Perhaps the reason is elsewhere, but your kind of error is what occurs when the python command use the built-in version of python, not the one installed by macports (or homebrew).
If you installed python via macports, you could use this (always from python-poppler-st4 folder): /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 setup.py build sudo /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 setup.py install If it doesn't work, could you copy the text from the terminal ? -- View this message in context: http://lilypond.1069038.n5.nabble.com/frescobaldi-on-mac-tp139401p143414.html Sent from the User mailing list archive at Nabble.com. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
