[Slackbuilds-users] numpy builds w/problems

Sun Mar 20 08:07:16 UTC 2022

Apparently; I reinstalled saved packages: now mathics 4 works on 
Slackware64 15.1+current w/earlier numpy & OpenBLAS.  However beforehand 
I removed numpy3 and now was trying to rebuild because no longer could: 
something else happens with that which I'm waiting on another attempt to 
save output to a TXT...
