OK, as usual, I need to retract some statements. See below.

As explained on the octave-help list, loadimage is only for the .img format.
Now I understand.

After some fiddling, and export CVSROOT=/cvsroot/octave, I was able to get
octave-forge from CVS. I figure having the latest will avoid the classic
"It's already fixed in CVS" answer. I borrowed a configure script and
configure.in from octave-forge-2006.07.09, and attempted a build, but ran
into errors during make. So I guess my corrected question is about how to
treat CVS octave-forge. Should I build with it, or just use it as a source
for test routines? If I build, where do I get the configure script info?

Thanks.
