That is probably a bug related to tracking down dependent typelibs.  Maybe
you could add an entry at sourceforge?

Note that in Python, "out" values (including in-out) are always *returned*
from the function.  Thus you probably want something like:

rc, newVals = oViTest.Call(arParNames,arParVals)

where 'rc' is whatever 'Call' returns - or, if 'Call' has no return value
(ie a 'void' function, or 'procedure'), simply:

newVals = oViTest.Call(arParNames,arParVals)
