That usually means that the software is missing some dependencies. If
you think they should be available in the build environment,
double-check that they are, and then look into how the software is
looking for them.

Also, Python software seems to change a lot, and quickly — make sure you
are using the correct version of all the dependencies.

Are you using the python-build-system? It should handle this problem
with its 'ensure-no-mtimes-pre-1980' phase.

In general, Python packaging is on the easy side but, when it gets
complicated (e.g. due to unusual design of the upstream build scripts),
it can be really complicated.

If will help if you share your package definition.
