Neither hp-check nor any hp-* programs work, and I can't print to my HP printer at all

# hp-check
Traceback (most recent call last):

  File "/usr/share/hplip/base/utils.py", line 42, in <module>
    import xml.parsers.expat as expat
ImportError: No module named xml.parsers.expat

BTW, I tried the non-packman packages first; no difference.

Help? How do I use this printer? Thanks.
