[ase-users] TestSuiteError

[Katsunori_Makino at n.w.rd.honda.co.jp]

Dear Sir:

I have found that "testase.py" is in python-ase-3.1.0.742.tar.gz,
not in the stable version.
.
Here is the log of the test suite, which shows ERROR.
(In my computer. (RHEL4.5, python 2.3.4, numpy 1.0.3)

Is matlabplot.py necessary?
