 PSMTabBarControl, probably from
                      https://github.com/dorianj/PSMTabBarControl
                      [PowerPC: maccode.googlecode.com]
                   and handled differently; note that the version
                   at from maccode has a bug on dealloc() and
                   uses methods that are now deprecated


Patches:
 cairo/src/cairo-path-fixed.c:1295: [from Cairo repo, 3/18/11]
   /* This check is valid because the current implementation of
     * _cairo_path_fixed_is_box () only accepts rectangles like:
     * move,line,line,line[,line|close[,close|move]]. */
    buf = cairo_path_head (path);
    if (buf->num_ops > 4)
	return TRUE;
 glib/glib/gconvert.c:61: comment out #error near

Configures (where <dest> is some temporary area):
  pkg-config: --prefix=<dest>
  libpng: --prefix=<dest>
  pixman: --prefix=<dest>
  Cairo: PATH=<dest>/bin:... --disable-xlib --disable-ft --disable-fc --prefix=<dest>
  gettext: --prefix=<dest>
  libffi: --prefix=<dest>
  glib: PATH=<dest>/bin:... CFLAGS=-I<dest>/include LDFLAGS=-L<dest>/lib --prefix=<dest>
   [PowerPC: after configure, set "allow_undefined_flag" to "" in "libtool";
             add "-lresolv" to link command for "libgio"]
  Pango: PATH=<dest>/bin:... --without-x --with-included-modules=yes --with-dynamic-modules=no --prefix=<dest>
   [PowerPC: same as glib for "libtool"; use PATH for `make', too]
  gmp: --prefix=<dest>
  mpfr: CFLAGS=-I<dest>/include LDFLAGS=-L<dest>/lib --prefix=<dest>

 To support 10.4, add
  CC=gcc-4.0 
  CPPFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.4"
  LDFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.4"
 for all packages.

 Note: PATH above ensures that pkg-config binaries are used to find
 things in <dest> rather than some other area, such as /opt/local.

 Be sure to use two-level namespaces for all libraries. While
 two-level namespaces are the default on Mac OS X, some packages turn
 on flat namespaces, at least on PowerPC. Use `otol -vh' and look for
 "TWOLEVEL" in the output to check that a library uses two-level
 namespaces.

XCode:
 Build PSMTabBarControl. You only need the Framework target, and
 in Release mode (which is "Build for Archiving" in Xcode 4.5).
 Use `ditto' to reduce the framework to one architecture.

Install:
  racket install-libs.rkt <dest>/lib
   * using `racket' for the target installation
   * do not include a trailing slash
   * double-check installed libraries to ensure that they do not
     have <dest> in their shared-library paths

  Also copy "PSMTabBarControl.framework" into the installation's "lib"
  directory. You can flatten all the auto-version soft links (moving
  "PSMTabBarControl" and "Resources" to immediately inside
  "PSMTabBarControl), and you can use `ditto' to prune the binary to
  just the platform that you're using.
