BUG: wrong libpng12.pc generated by libpng 1.12.0 port

[pelopor@…]

I have just installed the new libpng 1.2.10 port on my PB G4. After that some other port depending on it go into mess. I tried to reinstall those ports without success. Then I found that the 'libpng12.pc' file generated by DP in ${prefix}/lib/pkgconfig is really wrong. It reads:

prefix=@prefix@ exec_prefix=@exec_prefix@ libdir=@libdir@ includedir=@includedir@/libpng@PNGLIB_MAJOR@

Name: libpng Description: Loads and saves PNG files Version: @PNGLIB_VERSION@ Libs: -L${libdir} -lpng@PNGLIB_MAJOR@ Cflags: -I${includedir}

It shoud be like:

prefix=/opt/local exec_prefix=${prefix} libdir=${exec_prefix}/lib includedir=${prefix}/include/libpng12

Name: libpng Description: Loads and saves PNG files Version: 1.2.10 Libs: -L${libdir} -lpng12 Cflags: -I${includedir}

Then I looked into Portfile, then libpng's src, to find 'libpng-1.2.10/scripts/makefile.darwin' scritp has no effect to generate 'libpng12.pc' correctly. It is necessary to patch or manipulate that make file (or libpng-1.2.10/scripts/libpng.pc.in').
