   As mentioned in the build instructions, you need to have python3 installed. This isn’t an issue with bitcoin, just install python3 and run again :)

   Was python 2 deprecated?

   RHEL 6 & 7 are still using python2. Withal, RHEL6 doesn’t have python3 in default repository.

   Actually we did not yet deprecate python2 in make && make check.

    RHEL 6 doesn’t have a c++11 compiler by default either, does it? At least gcc 4.4 is below the minimum version (4.7) we support: https://access.redhat.com/solutions/19458 I guess we care about RHEL 7 though.

    laanwj, for RHEL, there is “devtoolset” repository with a later GCC versions. https://www.softwarecollections.org/en/scls/rhscl/devtoolset-6/
