While playing netris on Gentoo, I noticed some features present in the Debian version are missing. The ebuild applies a Debian patch (netris_0.52-7.diff.gz) but fails to apply the patches contained in that patch. Netris ends up being built without the Debian changes included. Please change the ebuild to also apply the Debian patches.
quite the oversight there. thanks for the bug report. fixed in -r1 plus bumped the debian patch version to 9.
