This is happening in the library, which doesn't read the config file,
and doesn't depend on the environment.  if a user tells the library "use
this as your gpg executable", it seems nice to fail early for them.

It's also nice if we want to have a default that says something like
"use gpg2 if it's available, but gpg otherwise".
