How does native support show up - as binaries are available and the compilation step can be skipped? > so I thought it might be nice to switch to it. > But even if I switch to the latest CentOS7 I will need to maintain 2 > sets of binaries while I switch. > > For example R is one that my scientists use a lot.

If I need newer versions of some libraries, I put these in a shared location and use them also for older kernel versions. And for some software we buy, we even get only the binaries which are compatible to a wide range of kernel versions.

Unfortunately no.
