The attached patch to the Release 2.5 version of pdflib fixes a
problem building on SuSE Linux Enterprise 10 in which the build
was failing saying it didn't know how to build ``-lpng''.
It turns out that the included piece for the Makefile uses the
variables PNGLIBLINK and JPEGLIBLINK in dependencies so requires
file names here, not loader options. I put in a couple of loops
through the l_ldflags macro to test for the libraries since on
the 64 bit machines this may need to check multiple directories.
It also required adding ``-lpng -ljpeg'' to LDFLAGS to get things
to load properly.
Looking at the pdflib.spec file in the CURRENT version of pdflib,
it appears that it should have the same patch applied.
