I believe the above error is from a missing `xml2`, but there is
another trouble with the module after that, that WMS server returns
subsection Titles (e.g. "the next 4 layers are about ozone, and 
some explanation about what it is"), which is confusing the
ogc_services.py parser which expects only Titles subordinate to
and following Layers. Even after testing to see if the layer is
set it still gets out of order as the subsection Title overwrites
the layer's title before the next Layer is created.

I'll open a bug for that.

But the r.in.wms script from the command line should still work.
