Fink installs an OS X Application: GRASS.app. Deep in the app I found a Makefile that seems to tell GRASS.app to respect "GRASS_LD_LIBRARY_PATH". The Macports version does not install an app, and does not respect the GRASS_LD_LIBRARY_PATH variable. For some reason, shell-level LD_LIBRARY_PATH and DYLD_LIBRARY_PATH 's are also not respected (perhaps due to SIP?).

Can you please create a ticket for this? Then the developers reading
the grass-dev mailing list will get notified instantly.

thanks
