Hi guys,
I know this is pretty old - and I have no idea what could be causing it. Does
the latest release have the same problem?
Thanks - Charlie

Hi,
I think I might be stumbling across the same problem. I've had a wee dig around
and think I might have some further information, but I'm not entirely sure what
to make of it.
First of all, some background. We have a CI server to verify that the tests are
passing. It runs through the following process:
* Grab the latest code
* Create an empty RVM gemset
* Use gem bundler to install all the gem dependencies
* Run the test suite.
Sounds good? It is, most of the time. Once in a while, though, when attempting
to run the test suite, we get:
dlopen(/Users/ci/.rvm/gems/ree-1.8.7-2010.02@cruise-78296/gems/libxml-ruby-1.1.4/lib/libxml_ruby.bundle,
9): Symbol not found: _cXMLNode

This doesn't happen on all runs, and re-running the CI build with the same
commit often makes it work again later, so I'm reasonably(ish!) confident it's
not an app problem. This is a CI server that I'm not actively messing with
either, so I'm reasonably happy that the environment is stable.
So, I dug in a little. It's right, that bundle doesn't have the symbol it's
looking for. In fact, the bundle doesn't have any symbols:
$ nm libxml-ruby-1.1.4-broken/lib/libxml_ruby.bundle
0000000000000000 t __mh_bundle_header
U dyld_stub_binder
That's weird, right? Well, weirder still, none of the object files have any
symbols:
$ nm libxml-ruby-1.1.4-broken/ext/libxml/ruby_xml.o
produces nothing. So, gcc is producing a file without any symbols. What kind of
file is it producing?
$ file libxml-ruby-1.1.4-broken/ext/libxml/ruby_xml.o
libxml-ruby-1.1.4-broken/ext/libxml/ruby_xml.o: 80386 COFF executable not
stripped - version 30821
That's weird, because a correctly built version is a Mach-O 64 bit object file
as you'd expect:
$ file libxml-ruby-1.1.4-working/ext/libxml/ruby_xml.o
libxml-ruby-1.1.4-working/ext/libxml/ruby_xml.o: Mach-O 64-bit object x86_64
Apart from the generated objects and bundles, there are no appreciable
differences between the broken version and the working version:

The host environment here is Mac OS X 10.6.5, we're using Ruby Enterprise
Edition 2010.02 (1.8.7), and we're using the Mac OS X-supplied libxml2:
$ which xml2-config
/usr/bin/xml2-config
$ xml2-config --version
2.7.3
I have no idea where to go next while tracking this down! Any suggestions?

I see this, too. Both the reporting of 1.1.2 and 1.1.3 installed, and the
missing symbol. Curiously, my Leopard machine does not report a missing
symbol, and it has 1.1.3, 0.9.5 and 0.3.8.4 installed
