Log Message:
Updated to version 3.1.4.

Pkgsrc changes:
  - Incorporated new version requirements for p5-Archive-Tar and p5-IO-Zlib.

Relevant changes since version 3.1.3:
=====================================

- bug 4941: if the first sa-update run failed and wasn't re-run to successful
  completion, the local state directory would exist, and therefore SA sees no
  rules.  now, wait as long as possible to create the directory, and try to
  remove it on failure.
- bug 4997: increase module version requirements for Archive::Tar to 1.23 and
  IO::Zlib to 1.04
- bug 4966: fix major BSMTP bug, which rendered SA unusable with exim4 when
  BSMTP is used.
- bug 4899: Windows had issues with single quotes around filenames so certain
  things like pyzor, etc, wouldn't function.
- bug 4958: sa-update should work on Windows
- bug 4908: gtube.t test failed in non-english locales
- bug 4488: deal with potential memory leak due to Bayes and BayesStore
  circular references
- bug 4862: update macro values in update channels (ie: @@CONTACT_ADDRESS@@)
