This is the problem. Fix apt issue, and then install libpq-dev, and then
ruby will allow you to compile its library.
As for what is the problem with apt? No idea. Check full output of the
apt-get install command, and react accordingly.
This is not a bug in Pg. This is not even (most likely) a bug in Ubuntu.
depesz
p.s. how does windows fit in all of this? You mentioned that you have
the problem on Windows, but then you say that you install Pg on ubuntu
(which makes sense given apt-get command). So which is it?
