I'm not so sure about that. What this means is that the test program that tried to test linking against libpq failed to compile. Most obviously this would be because libpq can't be found but doesn't look like it in this case. Like I said before i would play around with the LDFLAGS environment variable and see if you could use that to make it link against the kerberos library. The libpgsql-ruby library is basically the ruby postgres bindings (at least one of them - there have been a number of them over time, all with rather similar names), but installed via your package manager rather than as a gem. Assuming this library is the set of bindings that you do want you don't need the gem - you'd just end up with the same code installed twice, once as a gem and once not (although the timestamp in the version number for it makes it look quite old).
