@codebrainz wonderful, so:
1. make sure ldconfig is *not* in sudo's default PATH: `sudo env | grep PATH` and make sure it doesn't contain `/sbin` 2. build and install *in `/usr/local`* (e.g. don't give a custom prefix)
Hopefully this would not work in master, but work with this PR. If it does work with master, we'll have to make sure `sudo ldconfig` doesn't work because `sudo` doesn't fine ldconfig, and if it does figure out how to prevent it from doing so in order to test.
