Ebuild for gretl

Gnu Library gretl is a cross-platform software package for econometric analysis, written in the C programming language, http://gretl.sourceforge.net/. It is not in portage yet, and for a long time I couldn't get it installed on my Gentoo system (which is why I had that Debian excursion). Now finally I did it and with an ebuild!

The ebuild is based on Dan's attempt (http://bugs.gentoo.org/show_bug.cgi?id=39966) and should work on a stable Gentoo system. Here's the content:

Before you install it, don't forget to:

Code:
# ebuild /usr/local/portage/sci-mathematics/gretl/gretl-1.5.1.ebuild digest

first.
