Subject:   Why portmaster uses g++ not g++6 nor clang++?
Message-ID:  <0101016373cfd7a2-a231a144-9162-4315-82b5-93d3823e99b5-000000@us-west-2.amazonses.com>

Hi,

I'm building devel/qt5-make by portmaster. Somehow portmaster 
incorrectly detects gcc6 and
uses g++ despite it is actually installed as g++6. If I build it without 
portmaster, clang++
is used and build finishes successfully.

$ pkg info | grep gcc
gcc-ecj-4.5                    Eclipse Java Compiler used to build GCC 
Java
gcc6-6.4.0_7                   GNU Compiler Collection 6
gcc6-aux-20170802_1            Version of GCC 6 with full Ada support
gccmakedep-1.0.3               Create dependencies in makefiles using 
'gcc -M'
