Comment (by ryandesign):

 Chris, I can't come up with a quick fix for librsvg because it wants to
 offer different versions for i386 vs x86_64 and there are not separate
 PortIndexes at that level of granularity. (There is only one PortIndex for
 any Intel system for each OS version.) Also, as you already know the
 existing code does not work for the universal variant, so it needs a
 rewrite for that anyway.
