 Correct, i mean Clang in version 3.4 is hardmasked. I want install clang
 alone llvm i not need. I think mesa use llvm too but i has not set the
 use flag. 

1) clang-3.4 is not hardmasked either, so you need to set ~x86 keyword
for that package as well as for llvm - because:

2) clang is only a metapackage, without any contents on its own.
The compiler binaries are part of the llvm package. You simply cannot
have clang without llvm.

3) FreeBSD indeed uses clang as default compiler, but uses 3.3 since
3.4 still has quite a few new and exciting bugs.

Hope that clears things up.

Hi Silvio.  You're installing an ~x86 package on an x86 machine, I think.
Are you doing that on purpose?

I don't know if that is causing the error, but it sometimes causes problems.

Have i something not understand, i make emerge -av clang and become

gentoomobile siefke # emerge -av clang

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N~] sys-devel/llvm-3.4:0/3.4  USE=clang libffi ncurses python

Total: 2 packages (2 new), Size of downloads: 0 kB

The following keyword changes are necessary to proceed:
 (see package.accept_keywords in the portage(5) man page for more details)
# required by sys-devel/clang-3.4-r100
# required by clang (argument)
=sys-devel/llvm-3.4 ~x86
# required by sys-devel/llvm-3.4[clang]
=sys-devel/clang-3.4-r100 ~x86

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

Then emerge --autounmask-write -av clang and after dispatch-conf i run
emerge -av clang and become the error. I not understand what you mean?
