Fair point - I will try to use libxml2.la instead, as libtool knows
how to link to shared libraries portably. (Begs a question on how
ac_check_lib would cope, but I need to look into that more.)

-Wl,-R/usr/local/lib -L/usr/local/lib -lxml2 -lz -lpthread -lm

but because I added the -R - it isn't the default as distributed,
but seemed to be the right place to store the flags I need to
link to libxml.

So, feel free to drop the first part of that patch...

Patrick
