can't build cairo

[Kevin Layer]

I was able to build with gcc-4.2.   It would appear that this is
required to build on 10.5.

  export CC=gcc-4.2
  export MACOSX_DEPLOYMENT_TARGET=10.5
  export LDFLAGS="-arch x86_64 -isysroot /Developer/SDKs/MacOSX10.5.sdk"
  export CFLAGS="-arch x86_64 -isysroot /Developer/SDKs/MacOSX10.5.sdk"
  port install gtk2 +x11 configure.compiler=gcc-4.2
  port mdmg gtk2 +x11 configure.compiler=gcc-4.2

(I did get an error w/o the exports, but I didn't save it)

I'm having issues with the `jpeg' vs. `JPEG' library in running the
app this is for, but I hope to work on that this weekend.
