Description Alessandro Barbieri 2017-05-15 01:52:44 UTC 
I currently have llvm-4.0.0:4 (also clang ldc2 rust and mesa) and when I try to emerge julia (wich depends on >=sys-devel/llvm-3.9:0=) portage tells me of a conflict.

The question is: multiple versions of llvm can be installed on the same system?
eg. llvm-3.9 on slot 0 and llvm-4.0.0 on slot 4

here the output of portage

Comment 2 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-05-20 21:34:01 UTC 
Only 4 and newer can be installed alongside one another. 3.9 was before slotting, and is incompatible with it.
