Recompiled everything and made sure that directories were what I wanted.

I checked out the cvs version of sane.  The scanner now scans, but for a 
preview scan I get vertical colored lines in a black and white document  
When I scan, the image is rotated 45 degrees clockwise and the colored 
lines are still there--also rotated.  I can try to "hack" on the 
avision.c file--I'm not really very good at this--to see if I can find 
the differences between the cvs and the latest build.  Pointers?

I think I forgot to run "ldconfig" when I copied libusbscanner.  No 
permissions problem anymore. OOOOPS.  Sorry.
