Two possibilities occur to me.
1/ Since I am just looking for a way to eliminate "No repository set..."
and see you had the same concern once, if you actually solved that you
may be getting into the "...cyclic dependency check" which notes in the
code suggest may give an endless loop. I've skipped several details I
2/ You can get a lock condition with make -j 2. For example, I have a
test that can clobber a test db that another test is using, so I have to
be carefully not to run these in parallel. This is easy to check, if you
try without parallel make and don't have a problem then it is likely the
