I just did my usual:
make maintainer-clean \
&& ./configure --prefix=/usr/local/pgsql-serializable \
--enable-debug \
--enable-cassert \
--enable-depend \
--with-libxml \
--with-python \
&& make world
Which ended badly with the attached.
I've been running this pretty much every day on one or two machines,
and this is new.
