which is actually an issue with the version of pkg-config on CentOS 7:
$ pkg-config --version
0.27.1
Everyone should get a kick out of this: I had fixed this once before [1] but it was actually YOU, Marcus, that broke it again! [2]
I'll revisit the pkg-config version issue again. I think it was just the libtool version of commit 489762b that was causing heartburn (with Ubuntu 14.04, if I recall). I agree that the version requirement of libtool was probably over-specced, but it looks like we still need pkg-config >= 2.8.
A change like this will probably require regression testing on the major distros, do we want to wade in to the dangerous waters of identifying what those distros are? I guess I'm willing to set up docker images (like [3], which I need to update to install as a non-root user) to test Ubuntu 16.04/14.04 and CentOS 7. If there are other distros we want to hit we might need another volunteer.
