Comment (by ryandesign@…):

 Replying to [comment:1 ryandesign@…]:
 >  * The patch doesn't look right, but once the portfile sets build.env to
 include CFLAGS, CXXFLAGS and LDFLAGS to set the -arch flags, the patch
 won't be needed because the section of code it changes will no longer be
 reached.

 I've filed two additional issues for the situation you were correcting
 with the patch:

  * `-as-needed` doesn't work with Apple's `ld`:
 https://code.google.com/p/gpick/issues/detail?id=111
  * `-lexpat` is needed:
