Bug reported from a Sabayon linux system, based on the portage tree gentoo-x86:
 
 * ERROR: net-libs/webkit-gtk-2.4.9-r200::gentoo failed (pretend phase):
 *   You need at least GCC 4.7.x or Clang >= 3.3 for C++11-specific compiler flags
 *
 * Call stack:   
 *     ebuild.sh, line  93:  Called pkg_pretend
 *   environment, line 3962:  Called die
 * The specific snippet of code:
 *           die "You need at least GCC 4.7.x or Clang >= 3.3 for C++11-specific compiler flags";
 *
 * If you need support, post the output of `emerge --info '=net-libs/webkit-gtk-2.4.9-r200::gentoo'`,
 * the complete build log and the output of `emerge -pqv '=net-libs/webkit-gtk-2.4.9-r200::gentoo'`.

Can't be done another way.

What matters for the check is the *active* gcc version and that can't be a part of dependency calculation.

Thanks for the feedback. So it is kind of eselect wrong ? Would it be possible to talk about that eselect version in the error message ?

What is wrong with current message? Do you expect us to suggest to use gcc-config or similar? In that case, what is the "clang" equivalent for switching clang compilers?
