which will be why it failed.

always always always use the devscripts.

please DON'T use latest versions

+# pyvcd - needed for nmigen
+cd pyvcd
+git checkout 0.4.0 # latest version tested
+python3 setup.py develop --no-deps
+

eek please don't make arbitrary modifications to the devscripts
without first verifying FULLY that there is no damage done,
this is so critically important.

even if it takes days to re-run you MUST be patient and not
make arbitrary unverified changes.

pip3 list | grep vcd
pyvcd                           0.2.3

andrey please back that down to 0.2.4 real fast.

anyone who uses the scripts will find that they likely FAIL
causing us "support" issues and affecting our reputation.
