Thanks.

I tried git snapshots 20130227 and 20130228 on Fedora 18. I've never really had
to play with SANE before, so I'm ignorant of the architecture. I think I have it
built right, but I did install to its own tree under /opt/sane/backends/...

First, sane-find-scanner found it.

Then I ran 'scanimage -L' and it SEGV'd:

After that I have been fighting other issues with the ix500 no longer appearing
on my Fedora 18 laptop (which has two USB 3.0 ports). Not sure why ... need to
fix that before I can test again. 

I'll also try on a Fedora 17 box with USB 2.0 ports. It has a surprisingly large
number (145!) of dependencies on the sane*rpm packages, so I won't be able to
clean them.

What's the best way to run this out of /opt/sane/... without interference from
existing Fedora 17 / 18 packages?
