That's all correct. Though for OS X you might also need:

	LIBTOOLIZE=glibtoolize ./autogen.sh

as mentioned in cairo's INSTALL file, (so there are some notes in
cairo/INSTALL that should be copied down into pixman/INSTALL).

You've clearly got some pkg-config installed as your "port installed"
output shows:

>    pkgconfig @0.23_0 (active)

But this error:

suggests that aclocal did not find the pkg.m4 file and substitute the
PKG_CHECK_MODULES macro invocation properly. And sadly, it didn't give
you a kind error message at all.

So two things here:

   1. From talking in IRC, we know that you couldn't find a pkg.m4
      file anywhere on your system. So you should investigate how you
      came to have such a broken pkgconfig installation, (that pkg.m4
      file is its most essential component), and file a bug if
      necessary.

   2. Cairo's autogen.sh makes an explicit check for pkg.m4 and should
      have given you the following (hopefully more helpful) error
      message very early in the process:

	autogen.sh Error: Could not find pkg-config macros.
		(Looked in $acdir/pkg.m4)
		If pkg.m4 is available in /another/directory, please set"
		ACLOCAL_FLAGS="-I /another/directory"
		Otherwise, please install pkg-config.

		pkg-config is available from:
		http://www.freedesktop.org/software/pkgconfig/

So that's a check and error message that should be copied from cairo's
autogen.sh to pixman's.
