Package "pie" has invalid version

I just migrated from 8.7 to 8.10, and when running raco setup, noticed the following:

raco setup: --- checking package dependencies ---                  [13:18:06]
raco setup: invalid package version declaration:
raco setup:   package: "pie"
raco setup:   declared version: "0.01"
raco setup: --- summary of package problems ---                    [13:18:29]
raco setup: package has invalid version:
raco setup:   package: "pie"
raco setup:   version: "0.01"
