It looks like you've got -I/usr/local/include in front of the build's
own -I switches, and that's allowing it to pull in back-version copies
of PG-related include files instead of the ones in the source tree.

I'm not totally sure, but if you inject -I/usr/local/include through
CPPFLAGS not CFLAGS, configure might do the right thing automatically.
Otherwise, you could manually edit CPPFLAGS in src/Makefile.global
after configuring to get the right -I order.
