There is a small bug in libImaging/configure. If --with-jpeg is specified 
then configure correctly tests for -ljpeg in the specified directory, but 
does not add the given library path to the LDFLAGS used in the Makefile. This 
causes a compile failure for coretest, which needs to be linked against 
-ljpeg but doesn't know where to look for it.

I've fixed this by adding a "-L$withval" to LIBS in libImaging/configure, 
though it should really be fixed in the source configure.in. That file isn't 
included in the 1.1.3 source tarball, though.

The same problem likely exists for --with-zlib, but I haven't investigated 
that.
