It turned out I had an older conscript version installed that I didn't remove first.  Starting from scratch (deleting conscript and g8 installations) allowed me to install version 0.4.4 without this issue.

Conscript won't install - what to do?
I usually see 'satisfy the criteria' and 'meet the requirements', but is it acceptable to use 'meet the criteria', or 'satisfy the requirements'?
