I wasn't aware cutter was finally packaged in Fedora! That's a great news, I will fix it, thanks for noticing.
If you'd like to co-maintain (might make it easier to bump radare2 versions given how tightly they are coupled), I'd be more than happy to add you to the package's acl.
1) what's the difference between cutter-re and cutter packages?
"cutter: Unit Testing Framework for C/C++". Basically, the cutter name was taken...
2) is the problem only in cutter-re package?
Yes, considering cutter package is entirely unrelated.
3) is cutter-re shipped in f30 only?
