Regarding utop, it seems that you don't have in your $PATH. Did you do:

$ eval `opam config env`

If you want opam to be correctly automatically setup in your new shells you should add the following to your .bashrc:

. ~/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true

As for not being able to open Core.Std, you won't of course be able to open it in your shell, this command must be issued in utop.
