Looks like someone already noticed that the merge would fail because of this difference in host, and has chosen in the case of a universal build to replace it with "${os.arch}" (of the build machine) which would be either "i386" or "powerpc".

Misunderstanding: what I had in mind was to "replace it with [a version of] ${os.arch} (of the build machine) which would be either [x86_64 or] i386 or".
Which, incidentally, is "to modify the code of libgcrypt-config" in my book ;)

If libgcrypt works by loading parts (of itself) dynamically at runtime, it would be reasonable to print the kind of warning I saw when a mismatch is detected at build time.
The best approach would probably be to teach the libgcrypt build system of universal binaries, and come up with an appropriate solution. That's something we can leave to the port maintainer and the libgcypt developers, IMHO.
