It can't find augeas.pc; if you built and installed from source
(presumably into /usr/local), you'll need to set PKG_CONFIG_PATH and
LD_LIBRARY_PATH accordingly. Possibly other env vars, too. It's been a
while since I built against a non-default install of augeas.

Yes, the files should all be there. But not in places that mkmf looks
for.

If that's the only issue, try rebuilding the package. That might work
better than building the gem from scratch (and yes, gems are 18 kinds of
evil; unfortunately, they are also the way of ruby packaging)
