Basically it is missing -fPIC flags in several places (I just build it adding -fPIC to the CFLAGS in make.conf, probably incorrect, but I will find that out later, if stuff doesn't work.) During the Make phase it will quit on building the Xserver/xkb stuff, go into that directory "make", then goto the the .../work/xc directory and do make again will run to completion. Then ebuild ... install & ebuild .... qmerge will finish the job.
patch_ver 2.1.4 has the fixes
