Hmm, that is odd.  On the Windows system I am using
it works - but I don't recall if I did something
custom during setup ...

On the Windows system I am using the Enthought dist
(a Canopy version).  I am fairly sure pytest is
installed with the distro, if it wasn't I probably
installed via `pip`.

Ok, this seems to be an issue because I see the
same thing but I have no idea why (right now).
A quick look it seems the VHDL myhdl pck is
empty, it might be an issue with the latest directory
selection addition.

I see all the errors, on Windows only, with no mods.

Possibly but in general I think we want to make
sure things work on most major systems Python
support?  It is odd, from my background most
(not all) FPGA developers work on Windows and most
ASIC devs work on Linux.
