No, I did not try this.

No.  I saw it somewhere in a related build (proj, maybe?).  The build 
machine is pretty slow, so I tried to include everything that might 
possibly be necessary to avoid yet another rebuild.

This was due to a slightly broken jpeglib installation.  Apparently, 
jerror.h was missing from it.  This is no longer a problem.

I updated my local copy from CVS, configured without libtool, recompiled 
and now everything works fine.  Thanks for the help!
