python-dateutil will be updated to version 2.x and there may be changes that affect this package. If python-wstool will work with the newer python-dateutil, you can safely close this bug. If python-wstool really does require python-dateutil 1.5, please use Requires: python-dateutil15 for Fedora versions of the package until it can be updated.
Thanks for filing the bug report, Pete. I'll check and make the required changes. Warm regards, Ankur
`git grep` over upstream doesn't see any use of dateutil in this package, but there is some use of datetime. I don't think you need this Requires any longer.
