This is a request for an ebuild for the PDP++ package. It's a very popular neural network simulation package. I think that providing a PDP++ ebuild for the Gentoo community would be beneficial given the complexity of the compiling procedure and lack of support from author. http://psych.colorado.edu/~oreilly/PDP++/PDP++.html
No progress here for 1 year, closing WONTFIX. Feel free to reopen with an ebuild.
