It sounds like pysh in bitbake wasn't able to see a dependency on the
function in question. Creating a small/reproducible test case would be
how I'd approach it, there are tests on the pysh code in bitbake-
selftest for example.

Once I had a test case which failed, I'd then use that to debug and see
if I could figure out a fix.
