-----------------------------------+----------------------------------------
 Port: doxygen 1.5.9 +wizard (svn -r54420)
 Platform: Mac OS X 10.4.11 on a Powerbook G4 (Darwin 8.11.0/powerpc)

 Building DoxyWizard aborts with the attached linker errors.
 Two issues emerge from that:

 (1) Linking DoxyWizard does not find -lpng. The linker command line
     misses either an -L${worksrcdir}/libpng (yes, doxygen builds a
     static copy of libpng) or an -L${prefix}/lib.
     With respect to a given lib dependency port:libpng and a given
     post-patch action that inserts ${configure.cppflags} right
     after the compiler command, I have decided to insert
     ${configure.ldflags} right after the linker command as well.
     Thus, MacPort's libpng should be used. At least I hoped so.
     However, this still did not produce the desired linker command.
     (But I left the patch in for symmetry reasons.)
     Finally, I resorted to

         build.env-append        LIBRARY_PATH=${prefix}/lib

     within the definition of variant wizard. This helped.

 (2) Universal binaries are built without demand.
     First, I supposed that this is because there is a second
     post-patch definition for variant wizard which might override
     the previous post-patch definition.
     I have moved the post-patch and post-destroot commands out of
     the variant definition, and I have guarded them with a test for
     variant wizard or platform darwin where necessary.
     Note that the present patches to doxywizard makefiles can
     mostly be applied without regard to whether variant wizard is
     in effect, but the patches are appropriate for macosx/darwin
     only. Therefore, most patches are guarded by the platform test
     alone.
     Again, this alone did not help. (I left the patch in because
     having several post-patch definitions looks confusing anyway.)
     Finally, I found that addon/doxywizard/doxywizard.pro.in itself
     specifies "CONFIG += x86 ppc". I have added a patchfile to
     remove that unless the universal variant is desired.
     This made the difference.

 Some quirks removed by the way:

 (3) ${tmake_conf} was used in post-patch actions, but defined for
     platform darwin only.
     I have moved the definition into the post-patch section.
     Both the definition and the affected patch action are
     conditioned on a test for platform darwin now.

 (4) The build dependency bin:ginstall:coreutils is not needed.
     Just add --install /usr/bin/install to configure.args,
     and doxygen will use that. Also relevant for ticket #18400.

 I have attached a Portfile patch, an additional patchfile and the
 (previous) error excerpts. The patches succeed in building
 doxygen +wizard and doxygen -wizard correctly on my platform.
