I just ran the configure on a source installed version of Postgres and it worked.

What it was looking for:

checking whether to enable PostgreSQL support... yes
checking for PGSQL... no
checking default locations for libpq... found in /usr/local/pgsql/lib
checking default locations for libpq-fe.h... found in /usr/local/pgsql/include

And from the configure file:

{ $as_echo "$as_me:${as_lineno-$LINENO}: checking default locations for libpq-fe.h" >&5
$as_echo_n "checking default locations for libpq-fe.h... " >&6; }
if test -r /usr/include/libpq-fe.h; then
PGSQL_CFLAGS="-I/usr/include"
{ $as_echo "$as_me:${as_lineno-$LINENO}: result: found in /usr/include" >&5
$as_echo "found in /usr/include" >&6; }
elif test -r /usr/include/postgresql/libpq-fe.h; then
PGSQL_CFLAGS="-I/usr/include/postgresql"
{ $as_echo "$as_me:${as_lineno-$LINENO}: result: found in /usr/include/postgresql" >&5
$as_echo "found in /usr/include/postgresql" >&6; }
elif test -r /usr/local/include/libpq-fe.h; then
PGSQL_CFLAGS="-I/usr/local/include"
{ $as_echo "$as_me:${as_lineno-$LINENO}: result: found in /usr/local/include" >&5
$as_echo "found in /usr/local/include" >&6; }
elif test -r /usr/local/pgsql/include/libpq-fe.h; then
PGSQL_CFLAGS="-I/usr/local/pgsql/include"
{ $as_echo "$as_me:${as_lineno-$LINENO}: result: found in /usr/local/pgsql/include" >&5
$as_echo "found in /usr/local/pgsql/include" >&6; }
else
{ $as_echo "$as_me:${as_lineno-$LINENO}: result: not found" >&5
$as_echo "not found" >&6; }
_save_CFLAGS="$CFLAGS"
CFLAGS="$CFLAGS $PGSQL_CFLAGS"
ac_fn_c_check_header_mongrel "$LINENO" "libpq-fe.h" "ac_cv_header_libpq_fe_h" "$ac_includes_default"
if test "x$ac_cv_header_libpq_fe_h" = xyes; then :

So it is looking in the default source install locations. The RPMs I believe
install in different locations. Running configure --help shows environment variables
that can be set to change the configure search behavior.
