It looks like you are somehow linking to a pre-v10 version of
libpgfeutils.a.  Maybe that is installed in /usr/local/lib or someplace?

That's odd.  I think --with-libxml changes the set of -L directives,
which could be a mechanism to explain that, but it's sure not clear
why libxml would be bringing libpgfeutils along with it.

Note to hackers: seems like we'd better arrange for
-L../../../src/fe_utils to appear earlier in psql's link command
than it now does.  I think we thought we could get away with being
sloppy because we weren't planning on libpgfeutils getting installed
anywhere ... but that idea seems to have gone by the wayside.
