What ultimately gets done is up to you folks, of course.

As a near-term workaround, might I suggest putting something in the
online documentation telling OS X users to avoid later mkoctfile usage
problems by always using the "-Wl,-framework,foo" syntax rather than
just "-framework foo" when using frameworks?  This would apply for
configuring the Octave build as well as when they build tools that use
Octave.

That way they have a better chance of being able to hand-build Octave
and use "pkg install -forge <pkgname>" if they don't want to use a
package manager.
