[mythtv] OSX build issues and patches

Thanks to Geoff Kruse I found the osx-packager.pl script and have been
using that to try to build mythtv for OSX (Tiger).  It's been quite an
adventure, despite the script!  I've made some progress, which I'll
report here, and I think I need some help, too.

I've enclosed my current patch for the script.

* I'm trying to build a backend, so that's been enabled in the script.

* Many of the SourceForge download addresses in there wouldn't work
  for me.  I changed the script to use a different mirror

* FreeType is now at 2.1.10 and you can't get 2.1.9 anymore; updated

* I had some major issues because I had installed ccache with Fink
  Commander, but somehow the cache directory was set to /dev/null and
  I didn't know how to reconfigure it.  Since g++ becomes a symbolic
  link to ccache when it's installed, the QT test program that looks
  for the Mac version was failing mysteriously, and I could never get
  that #define set up.  From there on it looked as though gcc's
  preprocessor was broken.  I had to add -v to QT's configure options
  and watch messages carefully to even get a clue about this one.

* As part of one flawed attack at the problem above, I tried it with
  QT 4.  Its configure options are completely different.  I left those
  lines in the script, commented out, in case it becomes useful to

* After I got the QT mac version test program to compile, it wouldn't
  link.  Based on
  http://lists.trolltech.com/qt-interest/2005-05/thread00265-0.html I
  added -lobjc to the link line.  Since it seemed to have the answers
  I also added '-platform macx-g++' to the configure options.  I don't
  remember offhand whether that addressed a specific obstacle or if I
  just went on faith based on that article.  I know it was necessary
  when I was trying to work with QT4, so it may well have been needed.

* In libexif-0.6.12/libexif/exif-utils.c, line 86, exif_get_sshort is
  defined as static after being already declared without; I had to
  comment out the 'static' in order to make the compiler happy

* In qt-mac-free-3.3.4/mkspecs/macx-g++/qplatformdefs.h, 

    #define QT_SOCKLEN_T int

  needs to be 

    #define QT_SOCKLEN_T socklen_t

  in order to work with the latest system headers.

* Some QT things were failing to find -lXext at link time, and after
  mucking about with fink for *way* too long trying to find it (and I
  hope I didn't mess up my configuration), I realized it was already
  installed.  So I added -L/usr/X11R6/lib to qmake_opts and QT got

* mythtv seems to hardcode the use of distcc into its Makefiles, and
  OSX doesn't have a distcc binary available, at least, not from the
  usual places.  I had to download and build distcc from source.

* I'm now getting some link errors when building libmyth; I'm not sure
  how to address these.  Can anyone help?
