+Subject: [PATCH] Append CFLAGS and LDFLAGS to their Config.pm counterparts in
+ EU::CBuilder
+
+Since ExtUtils::CBuilder 0.27_04 (bleadperl commit 06e8058f27e4),
+CFLAGS and LDFLAGS from the environment have overridden the Config.pm
+ccflags and ldflags settings. This can cause binary incompatibilities
+between the core Perl and extensions built with EU::CBuilder.
+
+Append to the Config.pm values rather than overriding them.

+
+2011-05-16  Angel Velasquez <angvp@archlinux.org>
+    * perl 5.14.0
+    * Removed patch for h2ph warning from 5.12.3
+    * Removed provides array, you can use corelist -v 5.14.0 to know the
+    modules included with the perl core, through Module::CoreList (thx j3nnn1
+    for the tip)
+
+2010-11-07  kevin  <kevin@archlinux.org>
+
+    * perl 5.12.2-1
+    - Using /usr/bin/*_perl for script directories
+
+2010-11-06  kevin  <kevin@archlinux.org>
+
+    - Removed otherlibdirs directive from Configure
+    - Removed /usr/*/perl5/site_perl/5.10.1 from INC
+    - Finally removed legacy dirs /usr/lib/perl5/current and
+      /usr/lib/perl5/site_perl/current from @INC
+
+2010-05-23  kevin  <kevin@archlinux.org>
+
+    * perl 5.12.1-2

+
+    * perl 5.12.0-2
+
+2010-05-12  kevin  <kevin@archlinux.org>
+
+    - FS#19411.  Removed the for loop in perlbin.sh which didn't work on zsh.
+      This makes the loop variables unnecessary so the script no longer
+      pollutes the user's environment.
+    - FS#19427.  Added /usr/*/perl5/site_perl/5.10.1 to otherlibdirs to support
+      user built modules.
+
+2010-05-09  kevin  <kevin@archlinux.org>
+
+    * perl 5.12.0-1
+    - Modified perlbin.sh to only add existing dirs to PATH.  Fixes FS#17402,
+      path points to non-existant directories 
+
+2010-05-07  kevin  <kevin@archlinux.org>
+
+    - Added this changelog.
+    - Added -Dinc_version_list=none to fix FS#19136, double entry in @INC.
+      This removes the duplicates and versioned directory entries.
+    - Change scriptdirs to /usr/lib/perl5/{core,vendor,site}_perl/bin to fix
+      Fix FS#13808, binaries don't follow FHS.
+    - Stopped using versioned directories in sitelib and sitearch.
