Comment (by ryandesign at macports.org):

 This looks good, except that it doesn't work on MacPorts 1.6.0 (says
 `Error: Target org.macports.patch returned: can't read "universal_archs":
 no such variable`), and the patch uses inconsistent whitespace for
 indentation.

 I'll attach a revised patch which:

  * uses consistent tab indentation to match the portfile
  * sets `universal_archs` outside of the universal variant so it's set
 when the other phases come around
  * uses curly braces around all variable references
  * abstracts out the one change in the three `./Configure` invocations
 into a new variable `${my_cc}` and calls `./Configure` in just one place

 Problems that still remain:

  * the part that searches for differences between files assumes "i386" is
 among the requested architectures (not necessarily so if the user modified
 `universal_archs`)
  * the part that searches for differences between files checks for
 differences between "i386" and "i386" which it needn't do

 The `${first_arch}` code in the cairo port's universal variant may be
 helpful. (Note that the cairo port's universal variant is not working in
 cairo 1.6.4, but the mechanism is sound since it did work in 1.4.14. See
 #15451.)
