Hm, upgrading from the pike-7.8.866 ebuild gave me the follwing messages:
* * Installation of a directory is blocked by a file: * '/usr/lib64/pike/modules/__builtin.pmod' * This file will be renamed to a different name: * '/usr/lib64/pike/modules/__builtin.pmod.backup.0000' * * * Installation of a directory is blocked by a file: * '/usr/lib64/pike/modules/System.pmod' * This file will be renamed to a different name: * '/usr/lib64/pike/modules/System.pmod.backup.0000' *
It didn't prevent the installation from succeeding, but I'm now left with two obsolete files in /usr/lib64/pike/modules/...
