[Sébastien Labbé]

From branch 7.4.rc0 + #21689, I checked out branch 7.4.rc1 and "make start" works because "openblas" was not recompiled (why?).

But on branch 7.4.rc1, if I force compilation of openblas with "sage -f openblas", then I get the same problem I reported yesterday in the 7.4.rc0 thread.

Therefore, I will mark #21689 as a blocker so that it gets included in 7.4.

... I just realized Jeroen already set #21689 as blocker when he created the ticket.
