I don't know if you noticed, but the path name it was looking in was
underneath the libre-soc directory hierarchy, clearly being installed
contemporaneously with the other parts of the system.  That was one of
the first things I checked for.

I've tried uninstalling nmigen, and re-installing it from scratch, and
again it insisted on installing 0.1.

Just for grins, I tried with "cd nmigen && pip uninstall nmigen && pip
install -e .", and it gave me this result:

ERROR: nmigen-soc 0.0 has requirement nmigen~=0.1.rc1, but you'll have
nmigen 0.3.dev134+g30e2f91 which is incompatible.

Looks to me like there's a transitive dependency mismatch, and that is
what's causing the rollback to 0.1.

I've *ONLY* ever run nmigen in a virtualenv, and have never once had a
problem with it until now.  Something else must be the problem.  I
know it works, as my continued development of my Kestrel-3 and VDC-II
projects depend on it.

I did this.
