Sounds like a bug in the startup script to me since it should inherit
PATH and DYLD_LIBRARY_PATH. That is why we need more polish with the
dmg, but only the actual use will expose the problems :).
I will try to reproduce this and will open a ticket in case I can. If
anybody else can reproduce this please open a ticket and mention it in
this thread.

You can inject env values from the Python session, but I do believe if
you set it from inside Sage or python is is basically too late to have
any effect on the external launcher.
