I don't think there's anything official, but we discussed this to death 
a few years ago.  Handling GCC dependencies is the main issue and they 
change frequently.  I'm currently using the setup below on NetBSD 8 to 
utilize pkgsrc gcc8 in a local unprivileged tree bootstrapped by 
auto-pkgsrc-setup (http://netbsd.org/~bacon/).  I use the same kind of 
setup on CentOS.

I run pkg_chk periodically and haven't had any major problems with upgrades.
