Both versions of Kuroo currently in portage (0.80.2-r1 and 0.81_rc1) fail to build in GCC 4.3. The patch is trivial; some files are just missing an #include <stdlib.h>. I am attaching an ebuild for 0.81_rc1 along with the patch. I did not bump the revision because it's a build problem rather than a runtime problem (people who are not affected by the problem have no reason to update while people who are affected should simply be able to emerge it now). Please let me know if you think I should also attach an ebuild and patch for 0.80.2-r1.
Created attachment 149858 [details] kuroo-0.81_rc1.ebuild
Created attachment 149860 [details, diff] files/kuroo-0.81_rc1-gcc43.patch
Thanks, Nikos! Fixed in CVS.
