In the octave configure file I find tests for <Mach-O/dyld.h>. This
does not exist, but there is /usr/include/mach-o/dyld.h. On my system,
this is the same, and I see in the configure output indeed:
checking Mach-O/dyld.h usability... yes
checking Mach-O/dyld.h presence... yes
checking for Mach-O/dyld.h... yes
I bet that you have "no" here.
Also correct:
checking Mach-O/dyld.h usability... no
checking Mach-O/dyld.h presence... no
checking for Mach-O/dyld.h... no
...and very well spotted!

This is a big fat bug in the octave sources. I don't know where they
got this "Mach-O" from. It has never existed.
Funnily enough, they have a ChangeLog entry
2003-06-16 Per Persson <[EMAIL PROTECTED]>
* oct-shlib.cc: Include mach-o/dyld.h, not Mach-O/dyld.h.
They just didn't yet get around to fixing this in configure, too :-)
You can test if things work better if you make a symlink in
/usr/include from Mach-O to mach-o.
I did the test on my system, moved /usr/include/mach-o out of the way
and rebuilt octave. This gives me the same symptoms that you have been
seeing. So it seems that the code that they are using when Mach-O/dyld.h
is not found (using dlopen etc) is not working.
I am CCing the octave maintainer now, because octave-forge seems to be
an innocent victim in this affair.
