Debug help on x86_64

[Quentin Spencer]

I got an error trying to build octave-forge on x86_64 (the other archs
worked fine), and not having access to the necessary hardware, I'm not
sure how to debug it. It happens when configure is looking for
mkoctfile, a script in octave-devel that compiles dynamically loadable
functions for octave. The error I get is:

checking for mkoctfile... mkoctfile
/usr/bin/ld: cannot find -loctinterp
collect2: ld returned 1 exit status
configure: error: Could not run mkoctfile
error: Bad exit status from /var/tmp/rpm-tmp.65687 (%build)

So, it seems that mkoctfile is looking for libraries in the wrong place
on x86_64. This may be something I need to correct in octave itself, but
I'm not sure. Ideas?
