It seems to be the case. With GCC installed, by default I get no problems :
root(at)smadev:/usr/local/src/postgresql-11beta2# uname -a
FreeBSD smadev.internal.net 11.1-RELEASE-p4 FreeBSD 11.1-RELEASE-p4 #0: Tue Nov 14 06:12:40 UTC 2017 root(at)amd64-builder(dot)daemonology(dot)net:/usr/obj/usr/src/sys/GENERIC amd64
root(at)smadev:/usr/local/src/postgresql-11beta2#
root(at)smadev:/usr/local/src/postgresql-11beta2# cd /usr/local/src/postgresql-11beta2
root(at)smadev:/usr/local/src/postgresql-11beta2# ./configure
.....
config.status: linking src/makefiles/Makefile.freebsd to src/Makefile.port
root(at)smadev:/usr/local/src/postgresql-11beta2# echo $?
0

By looking into config.log :

configure:3885: checking for gcc
configure:3901: found /usr/local/bin/gcc
configure:3912: result: gcc
configure:3943: checking for C compiler version
configure:3952: gcc --version >&5
gcc (FreeBSD Ports Collection) 6.4.0

Now, if I configure for clang I get the error :
root(at)smadev:/usr/local/src/postgresql-11beta2# setenv CC cc
root(at)smadev:/usr/local/src/postgresql-11beta2# ./configure
......
checking for readline/readline.h... no
configure: error: readline header not found
If you have libedit already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable libedit support.
root(at)smadev:/usr/local/src/postgresql-11beta2#

As suggested, when using clang, the way to overcome is via :
./configure --with-includes=/usr/local/include --with-libs=/usr/local/lib
