Update Module::Build to 0.35

0.35 - Thu Aug 27 09:12:02 EDT 2009

 Bug fixes:
 - Fix t/destinations.t segfault on 5.6.2

0.34_06 - Sat Aug 22 21:58:26 EDT 2009

 Bug fixes:
 - Multiple test fixes for OS2 [Ilya Zakharevich]
 - Generated.ppd files use :utf8 if possible (RT#48827) [Olivier Mengue]
 - Fixed preservation of custom install_paths on resume (RT#41166)
   [David Golden]
 - Warn instead of crashing when Pod::Man tries to create files with
   colons on vfat partitions on unix (RT#45544) [David Golden]

0.34_05 - Sun Aug  9 22:31:37 EDT 2009

 Bug fixes:
 - When auto_configure_requires is true (the default), Module::Build will
   only add last 'major' version of Module:Build (e.g. 0.XX) to
   configure_requires to avoid specifying a minor development release not
   available on CPAN [David Golden]

0.34_04 - Sat Aug  8 11:02:24 EDT 2009

 Other:
 - Added documentation warning that 'get_options' should be capitalized
   to avoid conflicting with future Module::Build options and changed
   the examples accordingly.

0.34_03 - Sat Aug  8 07:39:16 EDT 2009

 Bug fixes:
 - Fixed failing xs.t if /tmp is mounted noexec (RT#47331) [David Golden]
 - Fixed failing debug.t on VMS (RT#48362) [Craig Berry]
 - Prevent par.t from dying on error in .zip extraction [David Golden]
 - Fixed potential runthrough.t failure on 5.6.2 [David Golden]

 Other:
 - Archive::Tar changed from 'requires' to 'recommends' so non-authors
   without IO::Zlib can still use Module::Build to install modules
   [reported by Matt Trout, fix by David Golden]

+=head1 USAGE
+
+A DistGen object manages a set of files in a distribution directory.
+
+The constructor and some methods only define the target state of the
+distribution.  They do B<not> make any changes to the filesystem:
+
+  new
+  add_file
+  change_file
+  change_build_pl
+  remove_file
+
+Other methods then change the filesystem to match the target state of
+the distribution (or to remove it entirely):
+
+  regen
+  clean
+  remove
+
+Other methods are provided for a convenience during testing. The
+most important are ones that manage the current directory:
+
+  chdir_in
+  chdir_original
+
+Additional methods portably encapsulate running Build.PL and Build:
+
+  run_build_pl
+  run_build
