Wow, even Fedora 27 has 6.2.91 :-( (Even more, Fedora rawhide also has the same
version)

EPEL has 3.14 :(

Unfortunately, the packaging policy is to use OS libraries to build or install
the packages. This is why I got stuck.

I think that explains why I cannot build 2.3.0 on my build machines anymore. We
have 2.1.0 at the moment.

So in short: Unless EPEL and Fedora updates v8, we are unlikely to update the
plv8 package :(
