Also (someone correct me if I'm wrong), but I believe gfortran is used
in place of g77 as part of gcc >= 4.0 on ubuntu.  I think you want
libatlas-base-dev (from a quick look at the *ubuntu repo), as well,
though I've never used this package.  Someone else will have to
confirm if it works, as I know there have been problems with packages
in the past (on suse for me).

Also, for Kubuntu (at least on my install), the dir is /usr/include.
You might want to have a look and see which one contains your headers.
