[R-SIG-Mac] R.app and JGR.app and the PATH environmental variable

[Michael Li]

It depends on what is the parent process.

If you use terminal, bash is the parent process, which honors
environmental variables in .bashrc or /etc/profile.

If you launch the app in Finder, which does care about .bashrc, you do
not get the environmental variables set there.  Instead, you should
edit ~/.MacOSX/environment.plist   (see
http://developer.apple.com/library/mac/#qa/qa2001/qa1067.html).

Best, Michael
