Yes. That version is too old. It doesn't work with current osmlib.

0.5.2 works for me on my development machine, but I have problems on
other machines with it. It seems the libxml-ruby people are changing
some things around in the last weeks and have broken the library several
times in different ways. :-(
I have just checked in a version of the OSM parser that uses REXML
instead of libxml that could be used while we wait for the libxml stuff
to settle. Its going to be slower, though.
Change OSM::StreamParser to OSM::StreamParserREXML and OSM::Callbacks to
OSM::CallbacksREXML to use this.
I have also added a version of osmexport that uses this. Call
"osmexport-rexml" binary instead of "osmexport".
Of course this is very inelegant and hacky, but I don't have the time at
the moment to do it properly. This should at least give everybody a
working version to work with.
