You don't really need matplotlib installed for using ASE.  I've updated
the download page:

 https://wiki.fysik.dtu.dk/ase/download.html

So, you you can ignore the errors you got.

In the latest version of ASE, the io.py test will not fail if matplotlib
is missing - that was a bug.

Thanks for the report,
Jens Jørgen
