No, the problem that that message (along with several others) addressed was that the symbol _libiconv_open is missing from the x86_64 image in Apple's distribution of libiconv. You're building i386, and the symbol _iconv_open is present in both the i386 and x86_64 images.

The new (since january) gtk-osx-build-setup.sh replaces the jhbuild stock bootstrap.modules with a replacement that builds a new libiconv regardless of architecture. I suspect what happened is that you ran jhbuild bootstrap *without* specifying the architecture to setup_sdk() and so built libiconv and gettext as x86_64, so there's no i386 image to link to. The safest thing to do at this point is to wipe everything and start over. Anything short of that will risk linkage problems in the several dependent libraries.
