ebuild with sed to fix the problems

rr-5.2.0 explicitly codes '-std=c++11' in its CMakeLists.txt' but
dev-libs/capnproto-0.7.0 requires -std=c++14

Furthermore rr-5.2.0 needs an additional patch for -std=c++17 (provided by gcc-8.2.0 and above)

The attached modified ebuild includes to sed's to fix both of these.

Please explain the problem first. I don't understand the need for the patch.

It claims the build fails. Can you attach build.log and post emerge --info output?
