Hi Detlev,

Thank you for the prompt effort! Unfortunately, I can not see anything 
different, but before I go any further, I installed the latest version, but did 
not first uninstall.  Should I uninstall first?
                                 ^^^^^^^^^^^^^^^^^^

So, on CLI the dialog is:

ak at supremo:/dat/work/py3/vectors32/vectors32-tst$ python3 testVectors32.py 
vectors32 module verification:
If no errors reported, all is well.
ak at supremo:/dat/work/py3/vectors32/vectors32-tst$ 

When the testVectors32.py is opened in eric5, the debugger opens doctest.py on 
line 1361, which is

encoding = save_stdout.encoding

and the error message is 

'Async File' object has no attribute 'encoding'
File /var/lib/python3.2/doctest.py line 1361

The vectors32 module is on the pypi index - it is not big, with IMO decent 
documentation, though I am biased - I wrote it.  You are more than welcom to 
try it.  If you wish, I could send you the tar ball, though pypi I think is 
easier.

Kind regards,

Al.
