pcase probably doesn't exist in all the ancient Emacs versions that you
want to support? In any case, it will case cause needless loading of
pcase at run-time. I'd use good old `cond' if I were you.
Actually, `if' will suffice in this case.
Actually actually, why not
  (if (executable-find "ctags-exuberant") "ctags-exuberant" "ctags")
?
