OK; it really is failing because it can't find the JPEG library
(library failures are often more involved, e.g. a library may need
other libraries which can't be found).

You probably need something like:

	--with-jpeg-libs=/sw/lib

The file in question will probably be called libjpeg.a or
libjpeg.dylib; you need to specify the directory in which that file
resides.

If a lot of the external dependencies are in /sw/include and /sw/lib,
it may be better to just use e.g.:

	--with-includes=/sw/include --with-libs=/sw/lib

so that those directories are searched for every dependency.
