A double slash doesn't matter.
Check the typelib with `strings
path/to/bundle/Contents/Resources/lib/girepository-1.0/Pango-1.0.typelib | grep
libpango`. It should also say @executable_path/../lib/libpango-1.0.0.dylib.
Since you're using a launcher script, is the actual executable (e.g. python) in
bundle/Contents/MacOS?
