Update from version 0.3000 to 0.3100 (upstream 0.31).

Pkgsrc changes:
 o Add a couple of dependencies needed when perl < 5.10
 o Add "c" to the languages; the tests use the C compiler

Upstream changes:

Revision history for Perl extension Module::Build.

 Deprecations
 - Use of attributes as class methods is deprecated (this was never a
   documented feature and appears to only have worked accidentally.)

0.30_02 - Mon Dec 15 12:23:55 PST 2008

 Bug Fixes
 - make Software::License dependency "softer".

0.30_01 - Thu Dec 11 18:25:53 PST 2008

 New Docs
 - Added a recipe for writing a new action to the Cookbook
 - Added a recipe for bundling Module::Build to the Cookbook.

 Doc Fixes
 - Clarified dist_abstract search procedure in API.pod (RT#41056) [Mario
   Domgoergen]

 Bug Fixes
 - Workaround HARNESS_TIMER env issue in t/compat.t (RT#39635)
 - Fix ~ expansion when $HOME is different from /etc/passwd as
   when running sudo.  [rt.cpan.org 39662]
 - Fixed a small POD error in the Cookbook. [Damyan Ivanov]
 - Unset group/other write permission bits when using Archive::Tar to
   build the dist tarball. (RT#39804) [David Golden]

 Enhancements
 - We now support a 'create_license' parameter to new() that will
   create a LICENSE file during the 'dist' phase with the full text of
   the license.  This requires Software::License on the author's
   machine.  THIS ALSO STILL NEEDS DOCS.
 - Added lgpl2/lgpl3 entries to the supported licenses (RT#40532).
 - Support for validating properties with a check subref. [David
   Wheeler]

 Test Fixes
 - Defend against more stray environment variables interfering
   with the tests.

 Other
 - Updated our embedded version.pm to 0.76, enhanced documentation on
   dist_version_from.  [John Peacock]
