Xorg Install Problem

[IcEonFirE]

Hi

After installing Gentoo, I tried installing X server by using emerge xorg-x11
but installation is failed with segmentation fault... I tried again and again and the problem is still the same. I Like to get help please:

[...]
Event.c: In function 'AddEventHandler':
Event.c:386: Internal compiler error: Segmentation fault
Please submit a full bug report
with preprocessed source if appropriate

[...]
