58+# No idea why the below is needed - build fails without these 59+#/usr/bin/ 60+#/usr/share/

Build obviosly does not fail anymore - why would you keep this in spec file?

48+mkdir -p %{buildroot}/usr/bin/ 49+mkdir -p %{buildroot}/usr/share/man/man1/

You seem to be upstream of this - I would suggest to use "install -D" in makefile ...

From build log: [ 12s] g++ -MM -c -Wall -O3 -std=c++11 -flto classifier.cc > classifier.d [ 12s] g++ -MM -c -Wall -O3 -std=c++11 -flto counters.cc > counters.d

opflags (distribution wide compiler flags are not honored), also -03 is usually strongly discouraged

CXXFLAGS ?= in make file should be used

why exactly is git buildrequired?

Are you aware that buildrequires means that package is available during build, but it does not make it runtime dependency?

If git is runtime dependency there should be Required: git

If git is really build dependency, you should buildrequire git-core to avoid slowing build via pulling unnecessary stuff ...
