Hi,
I believe the problem is due to some misconfiguration on
your side.
Specifically, I suspect that you compiled and linked
XML::LibXML against one
version of libxml2 library, but your configuration is such
that the dynamic
linker tries to link it with a different (probably older)
version at
run-time. The C part of XML::LibXML doesn't use this symbol
specifically.
BTW, putting Perl modules to /etc seems really exotic to me,
but you didn't
specify your platform.
XML::LibXML's Makefile.PL uses xml2-config by default to
detect libxml2 setup,
but you can also specify the right paths via LIBS=... and
INC=... manually.
You can also use DEBUG=1 to see what happens. I would also
try running
ldd /etc/XML-LibXML/blib/arch/auto/XML/LibXML/LibXML.so
and other magic to see if it gets linked against the correct
libxml2.so.
P.S. since Perl bindings are not official part of libxml2,
you might prefer to
discuss this on a Perl forum at perl-xml listserv.activestate.com. OTH, it
would most probably be just me replying there and without
more details, I
can't really help.
