The links are there...

...so, not surprisingly, there's still no symbol definition:

# nm -C /usr/local/xerces-c-src_2_3_0/lib/libxerces-c.so.23.0 | grep -i isanyslash

Jason> Do this:

That solves the problem.  The module loads and the vast majority of the
tests pass.

I still have a couple of failing tests, though.  Here's the 'make test'

Failed Test       Stat Wstat Total Fail  Failed  List of Failed
t/AttributeList.t  255 65280     8    6  75.00%  6-8

12 subtests skipped.
Failed 2/35 test scripts, 94.29% okay. 3/35353 subtests failed, 99.99% okay.

Here's the verbose output from the failing tests:

I'll do a little testing/coding of my own with it next week and I'll let
you know how that goes.
