Description Malte E. 2016-06-30 13:20:37 UTC 
When I try to emerge qtscript 5.6.1, it fails as follows:

>>> Emerging (1 of 1) dev-qt/qtscript-5.6.1::gentoo
 * qtscript-opensource-src-5.6.1-1.tar.xz SHA256 SHA512 WHIRLPOOL size ;-) ...                                                                                      [ ok ]

gcc 4.9.3 is installed, so this must be a faulty check. Also, this seems to be in the ebuild, so I am filing the bug with Gentoo.

Reproducible: Always
Comment 1 Michael Palimaka (kensington) gentoo-dev 2016-06-30 14:31:07 UTC 
4.9.3 may be installed, but what is the active compiler?
Comment 2 Malte E. 2016-06-30 23:06:53 UTC 
GCC 4.9.3 and clang 3.7.1-r100 are the only two compilers installed. I'm not using clang for anything other than llvm itself.
Comment 3 Malte E. 2016-06-30 23:15:59 UTC 
it appears I was wrong. I was indeed using clang to compile, for whatever reason. Sorry about that.
Comment 4 Davide Pesavento (RETIRED) gentoo-dev 2016-06-30 23:34:56 UTC 
Reopening, we shouldn't reject clang.

I already knew about this limitation, but was waiting for something like https://gitweb.gentoo.org/repo/gentoo.git/commit/eclass/toolchain-funcs.eclass?id=2fea606eba41d9246f510814ce833879368bd835 to be implemented.
