I would rather say "one tarball, one package". But this case is borderline: 
The python bindings are not installed automatically, but need an additonal 
"python setup.py" step in a subdirectory, which even compiles a shared 
library. And they can be downloaded in a separate tarball.

Are there any other opinions? So far, I modified the existing package to 
also install the bindings, but they could easily be split out.

Yes, I needed to add
   (setenv "PYTHONPATH" (string-append libxml2 "/lib/python2.7/site-
packages"))

as well as in some other place
   (setenv "PERL5LIB" (string-append perl-xml-parser 
"/lib/perl5/site_perl"))

This had better be handled centrally. One could do it in the same way as 
CPATH currently, but Ludovic had some ideas how to generalise it even 
further. I added a "FIXME" comment in the build recipe.
