This returned:

I set it to look for the modules path using getenv and now I am getting
some errors. Maybe I can copy libevdocument.2.dylib to
libevdocument.2.soor something. libevdocument.2.dylib exists with
/jeremiahbenham/Desktop/Denemo.app/Contents/MacOS/../Resources/lib. I
placed it in my LD_LIBRARY_PATH. Here is the error:
