dispcalGUI 2.6.0.0 is out (in fact 2.6.0.3). I renamed the 2.5.0.0 ebuild to 2.6.0.3 and it compiled fine. Reproducible: Always
Marios are you happy with a simple rename of the 2.5.0.0 ebuild?
I couldn't find any 2.6.0.3 tarball so i just bumped it to 2.6.0.0 Thanks
They keep their tarballs on sourceforge: https://sourceforge.net/projects/dispcalgui/files/snapshot/ 2.6.0.0 is fine, as 2.6.0.* other than 0 are considered to be testing.
