My build problem is fixed, thanks.

But I'd still like to understand how portupgrade can fix anything if
the dependencies given in the Makefiles isn't correct.  Does
portupgrade have any other sources of information than
/var/db/pkg/pkdgb.db, built from the information in the directories
under /var/db/pkg, which in turn comes from make install under
/usr/ports?

In the specific case, how would make in textproc/libxslt (Makefile
1.69) know that libxml2 should be installed before building?

:-)

Good news.  Thanks.
