>Description:
Port databases/postgis doesn't compile with CLANG, so setting USE_GCC=4.6+ should build the port avoiding CLANG. but port switches compiler by force:

        ! databases/postgis (postgis-1.5.3_2)   (unknown build error)

>How-To-Repeat:
Have FreeBSD 10/9.1 built with CLANG and set /etc/make.conf properly to build eveything with CLANG.

Have either a file /usr/local/etc/ports.conf which contains

# databases/postgis
.if ${.CURDIR:M*/databases/postgis}
USE_GCC=                        4.6+
#CC=                            cc
#CXX=                           c++
#CPP=                           cpp
.endif

or manipulate databases/postgis/Makefile adding USE_GCC=4.6+

Try to compile the port and watch ghost switching compiler (due to misrespecting CPP?)
