Problem with scipy and associated ports (dependent libraries etc. ) missing symbols causes error, LAPACK problem?

[NeilBowles]

Hi

I suspect this is to do with the recent scipy 1.2 build and LAPACK issue reported by others. When trying to import pretty much any function from scipy (in this case "integrate" but fails on everything else I've tried) import fails due to a missing symbol (_cbbcsd_). I suspect this breaks everything that requires scipy so apologies in advance if there are additional tickets.

trace back below:

The error appears to be the same as #57829. Please tell me if not - I'll reopen this ticket.

Yes this ticket looks the same as #57829, which I (hopefully) just fixed.
