No need to apologise, and yes that was exactly what I suggested. I am the one who should apologise, because I didn’t test it, just guessed it.
I should probably just butt out leave this to @harshula.
Having said which, @dkhutch’s tip for debugging the builds seems like a good one
spack -d -v install > install_log.txt 2> error_log.txt
Feel free to so that and upload the error log here, or DM it directly to myself and @harshula.
