Error(s) that match a know pattern in addition to what has been reported in the summary:


sed: can't read ./Makefile.in: No such file or directory
configure.ac:171: error: required file 'unix/config/ar-lib' not found

tinderbox_musl has reproduced this issue with version 3.7.0.0-r4 - Updating summary.
