gandalf not found problem

[Jichao]

After following the command, gandalf is not found.
It seems that the opam does not insert .opam/system/bin/ into PATH environment variable. Maybe add this to the readme?

@Jichao opam adds its own to the PATH. Most likely you have a out of sync switch, check $ opam switch and most like you'll need to do a eval $(opam config env)

Thanks for your reply, eval $(opam config env) gives file config not found. Anyway I manage to add it to system path manually.

Okay glad you got it fixed but file config not found doesn't sound good. Can you give more output, like what exactly is printed when you do the eval $(opam config env)
