When emerging guile on 4-processor system and have MAKEOPTS="-j 5", it fails with error complaining some missing file (sorry, lost which one), which is generated by other process. Commenting out MAKEOPTS resolves this problem Reproducible: Always Steps to Reproduce: 1. emerge guile Actual Results: It finishes with error complaining about missing file Expected Results: It should compile without error Removing MAKEOPTS (-j 5) fixes this bug.
alright, disabling parallel builds for guile-1.6.4-r1.
