This problem is still happening.  Here's the most successful evaluation
we've had in a while:

  http://hydra.gnu.org/eval/66919

Here are some builds from that evaluation that failed because the
derivation had been deleted:

  http://hydra.gnu.org/build/48451 (asciidoc i686)
  http://hydra.gnu.org/build/48070 (boost i686)
  http://hydra.gnu.org/build/48516 (glib x86_64)
  http://hydra.gnu.org/build/48385 (lapack x86_64)
  http://hydra.gnu.org/build/48494 (python-setuptools x86_64)
  http://hydra.gnu.org/build/48018 (gpgme i686)
  http://hydra.gnu.org/build/48336 (libxdamage i686)
  http://hydra.gnu.org/build/48459 (libxkbfile i686)
  http://hydra.gnu.org/build/48402 (libxmu i686)
  http://hydra.gnu.org/build/47928 (mailutils i686)
  http://hydra.gnu.org/build/48511 (samba i686)
  http://hydra.gnu.org/build/47968 (shadow i686)

All of these are from the last day or two.
