It's unlikely that all of these users have made the same unfortunate change, instead it's likely that the various upstreams are experiencing a coordination failure.

Oh, the irony of it all! given that autoconf and friends are supposed to do that figuring out, and do it *portably*.[1] More specifically, from a quick look at configure.ac, it is clear that program does not consider pkg-config to be a hard requirement of Emacs (and INSTALL doesn't say so, although INSTALL.REPO does). ISTM that configure should test for a working pkg-config, and warn the user about breakage at that point (preferably with useful advice for a remedy). Blowing up in the middle of a test for an unrelated feature that happens to use pkg-config is not user-friendly. A review of configure (trunk updated from bzr today, I assume bzr is still current?) suggests that Emacs should be buildable with no pkg-config at all, you'll just be missing a pile of features. Patches welcome, I know. Sorry, not high on my priority list. Footnotes: [1] That's the excuse for the whole insanely complicated mess!
