 When building cairo universal I had to change the Portfile.
 I am building on leopard/ppc and I want to let this run
 on tiger/intel.

 I was building cairo with:
 port install cairo +universal +no_x11 macosx_deployment_target=10.4

 which does the job when I use --host=i686-apple-darwin8 and --host
 =powerpc-apple-darwin8 like can be found in the patch.

 Now it really beats me, when I want to merge my changes to a new Portfile
 under the circumstances, that this should only be used
 when building from leopard/ppc.

 I was trying something like

 platform Darwin 9 powerpc {
    //  my configure here
 }

 but it gets ignored.

 Kind regards
 Thomas
