Unfortunately, not so easy. Once the libiconv in the bundle is loaded, dyld won't load any other ones, so you still get the error from libcups.

Having dl'd the sources for Apple's libiconv, it appears to have diverged substantially from gnu's. I originally included libiconv into the gtk-osx build because of problems with x86_64; that turns out to have been the wrong solution.

I think the solution is to remove libiconv and rebuild everything; the automake macro which (incorrectly) decides that it's gnu-compatible will have to be fixed.
