Ok, so I'll try and make a note in our README.  It does seem broken that
the header file is found but not the library (linker and compiler are
out of sync...)

It's not just make check.

If I add a note to our README does is there any difference between:

  LDFLAGS=-R/usr/local/lib

and

  LD_RUN_PATH=/usr/local/lib

I'm using automake and libtool as well.  Plus, the package builds both a
shared library and an application that links against that shared
library.  Maybe that's why I'm seeing the -R difference on the link line
when --prefix is used.

Thanks very much for the help.
