Version 0.31.0 of the wheel package started using metadata version
2.1, which is not supported by versions of pkginfo earlier than
1.4.2. Upgrading wheel without upgrading pkginfo will leave the
env unable to read pkg info generated in wheels. Utils like twine
rely on this and will break.
This is a check to confirm that the metadata generated by wheel
can be read using pkginfo.
