As a maintainer of math/openturns, could you have a look at PR #252648:
In short, TBB version 2021 will soon be available as devel/onetbb and (good news!) the port you maintain seems to build correctly with that new version, see the following Poudriere run:
and build log:
Can you check the port and see if it is working as intended with the attached patch ?
If yes, please agree with the patch *by replying to this PR* (important), that will help me synchronize the changes.
To help you testing your port, expected patches to devel/tbb and devel/onetbb are available in PR #252648.
You will also need suitesparse patches from PR #252651 as suitesparse does not build with oneTbb.
Thanks for your contribution,
