A common mistake would be to add it in the form
Many (most, I think) shells don't do tilde expansion in quoted strings, so
you'd have a literal '~' in your PATH. That's no problem if it's passed to
a shell, but other programmes usually don't do expansion for such strings.
If that's the case here, possible fixes are
- spelling it out
- using $HOME instead of ~
- not quoting

Also if the other cabal is in a place before $HOME/.cabal/bin in the PATH.
