As postgresql84 does not currently build correctly universal for x86_64/i386 however it (presumably) can build for i386

and

as wxWidgets (as dependency for py26-wxpython) needs 32-bit (because it does not build 64-bit yet, this from a personal answer from Jyrki Wahlstedt)

does this mean that, provided I am happy to lose 64-bit or build them selectively for those which had no interacting dependencies / dependents, then I could just set 

build_archs i386

and would I need to do some kind of purge-and-rebuild? Then what I need which cannot build universal and/or which for any other reason would not build 64-bit should then work?
