However, while the load path is being set properly, load-extension in Guile is looking for dylibs in the wrong place (specifically, in LilyPond.app/Contents/Resources/var, as well as a couple of related paths and some /usr/lib-type directories). I can't figure out how to change that setting, and Guile's docs are not very clear on how to set the extensiondir. Any ideas before I just give up and put the libraries in var?
