Qt 4.3.4 does not build with the system compiler on FreeBSD

Qt 4.3.4 does not build with the system compiler on FreeBSD, it bails out while building the PostgreSQL driver with the following error

Update:

The basic problem is that the configure script is putting the local
/usr/local/include location earlier than the build-local include
directories in the compile line. The submitter of task 201483 has
installed another Qt version from FreeBSD's ports or packages, and the
build system for the postgreSQL driver is picking up the 4.3 headers.

Examining the built Makefile will show that there is a
-I/usr/local/include in the CXXFLAGS, rather than being limited to the
INCPATH variable.
