Thanks Brandon.  But I think Ben was probably right; I need cabal install cabal-install.  Somehow this ought to be easier.

 

I’ll try that when I next get a chance

Maybe I need 1.24.  Which claims to be installed.  But WHERE is it installed?


Try "type cabal". "which" has a nasty tendency to show you what the next shell you open (or sometimes the next time you login) will see; shells remember what they've already seen, so it's probably still running the old one (likely in /usr/bin or /usr/local/bin). POSIX requires "type" to show what the *current* shell (thinks it) knows, not what some future shell will see.

 

"hash -r" should work to reset the shell's idea of where cabal is, if "type" says it's running a different cabal.
