I tried it with some ports and forgot to remove it. Today I saw it
again, changed it to explicit other values to test it.

src.conf does not exist here, and make.conf contains this:

# added by use.perl 2012-08-23 17:45:18
PERL_VERSION=5.14.2

CFLAGS=-pipe
#CC=clang
#CC=gcc
CXXFLAGS=-pipe
#CXX=clang++
#CXX=g++
