Your package perl-Math-NumSeq failed to build from source in current rawhide. http://koji.fedoraproject.org/koji/taskinfo?taskID=5738569 Build logs: root.log: http://kojipkgs.fedoraproject.org/work/tasks/8569/5738569/root.log build.log: http://kojipkgs.fedoraproject.org/work/tasks/8569/5738569/build.log state.log: http://kojipkgs.fedoraproject.org/work/tasks/8569/5738569/state.log NOTE: build logs are cleaned up after 1 week For details on mass rebuild see https://fedoraproject.org/wiki/Fedora_20_Mass_Rebuild
The latest upstream version is Math-NumSeq-62. Please update it.
I will update this once perl-Language-Expr will be able to build. Apparently, the dependency on Language::Expr is optional, but it enables some features. So I wouldn't cut it off, unless it's really the last option.
You might want to do a build without it until Language::Expr comes back, which would at least save you the daily nagmails about this package (and slic3r if that can be built too) having broken deps...
It builds without it, but slic3r does not, so I'm leaving this open.
This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle. Changing version to '20'. More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora20
Affects both Rawhide and F20.
Slic3r builds, so closing this one.
