--- Comment #11 from Jan Martin Mikkelsen <janm@transactionware.com> ---
I see this failure with many parallel package builds in a single jail. Redu=
cing
the concurrency (for example, down to 16 concurrent port builds on a machine
with 56 hardware threads) the problem mostly does not appear.

At the point of the failure, devel/py-wheel and devel/py-wheel044 had both
completed. On a system with a successful run, the devel/py-wheel build had =
not
completed.

In our build system, making devel/py-wheel explicitly depend on
devel/py-setuptools resolved the build issues.
