Steps to reproduce the issue
I have tried to build a package that depends on py-pyyaml, but py-pyyaml fails during the build stage due to what looks like a linker error. I am not sure whether this is due to the linker looking at the wrong place or if it is something else.
$ spack install py-pyyaml
==> Error: Failed to install py-pyyaml due to ChildError: ProcessError: Command exited with status 1:
