Apparently you also need to add the option --no-openpgp, as mcrypt
otherwise expects input in the OpenPGP format.

  $ mcrypt -a enigma -o scrypt --bare --decrypt --no-openpgp < /tmp/test
  Enter passphrase:

  Stdin was decrypted.

I don't know if this behavior is controlled by a configure option and
also could not spot any difference in a quick comparison with the Debian
package. No idea what what causes this.
