MarsSeed [1] filed a deletion request for squeak-sources-41 [2]: This is a source headers package for squeak-vm 4.1. Package last updated in 2015. But its dependent from Arch repo is squeak-vm 4.10.2.2614 - therefore this package is not useful to keep. There are no user comments, and nothing depends on it.
