Since neither that comment nor that code appear anywhere in the Dovecot
2.2.1 tarball, I have to assume you're using a patched version from a
SRPM or something. It would have been helpful to mention that; also
helpful to try with the unpatched version before posting.

Whoever patched that code in either didn't understand that Dovecot needs
lib and libexec to be different, or had a workaround of some kind. I
would recommend using the real 2.2.1 sources from dovecot.org instead.

That installation will not work, you've just tricked install(1) into
not giving you an error. Dovecot needs ${libexecdir}/dovecot/auth to be
an executable: it's one of the daemon processes, and if you've put a
directory there the exec will fail. Installing it to
${libexecdir}/dovecot/auth/auth instead won't help, since Dovecot won't
be looking for it there.
