So as I mentioned in previous posts, I use Gentoo as the distro on my primary desktop system. Recently, I was having some portage compiling conflicts so I decided to re-emerge most of my package to make sure package dependancies were all in sync and that the USE flags were considered for deep dependancies that needed them. It takes a while to perform this task, so make sure that you have some available downtime to resolve any bugs and issues.
The biggest frustration I had during this process was with libX11 as there was limited documentation on the issue I had experienced. Here was the focus of the error:
cd util && /usr/bin/make
make[2]: Entering directory `/usr/src/libX11-1.1.5/src/util'
make[2]: Nothing to be done for `all'.
make[2]: Leaving directory `/usr/src/libX11-1.1.5/src/util'
../src/util/makekeys < /usr/include/X11/keysymdef.h > ks_tables_h
/bin/sh: line 1: 3530 Floating point exception../src/util/makekeys <
/usr/include/X11/keysymdef.h > ks_tables_h
make[1]: *** [ks_tables.h] Error 136
make[1]: Leaving directory `/usr/src/libX11-1.1.5/src'
Well, there are two points that interested me in this error, the “Floating Point Exception” as well as the Error 136. Neither of which provided much assistance in the google searching. I finally found a bug report through following link after link. hopefully this article helps you to find the root of your issue faster: Bug Zilla Error 15111
Ultimately, you need to check the version of xproto that you have installed. By masking 7.0.15 and re-emerging 7.0.14, I was able to resume the emerge without any remaining libX11 errors.

thanks for the info ! i was having a similar issue and i never realized that i had put experimental version of xproto in the keywords file. once i took it out, and re-emerged, it all worked fine.
kind regards

No problem. I’m glad to see it worked for you.
