Well, better start double-checking, because it certainly appears that
the version of pg_config you're calling is not from a --with-libxml
build.
After thinking a bit, another possible way of messing this up would be
if you were working in a previously-used build tree, and simply did
a new configure run and then "make" without cleaning up the old build
products. You might be able to get away with that if you'd used
--enable-depend, but without it you really need at least "make clean"
and preferably "make distclean" before reconfiguring.
