если глянуть сюда https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=c5fca1c68a374712eb2a6b2fde6807c63b6a5f63 то дело в этом:
#if XORG_VERSION_CURRENT >= 11900000
#include <bits/sigset.h>
typedef __sigset_t sigset_t;
#endifсмотрим файл vim /usr/include/xorg/xorg-server.h:
/* Current Xorg version */
#define XORG_VERSION_CURRENT (((1) * 10000000) + ((19) * 100000) + ((5) * 1000) + 0)
т.е. версия явно больше чем 11900000... что делать?
