Zachary Ware added the comment: As this appears to be specific to Python 2.7 which has now reached end-of-life, I'm closing the issue. Thanks for the report anyway, and I'm sorry we couldn't get it a bit more straightened out before EOL! -- nosy: +zach.ware resolution: -> out of

Adam Stewart added the comment: > I'm certainly not going to try to deeply analyze a build that inserts *that* > many separate -I and -L options into the compiler calls I believe those were necessary to get the build working. Spack doesn't install anything into /usr/, and without those flags,
