perl/perl-update-Archive-Extract.patch
Štěpán Kasal 26b7a08961 - remove compatibility obsolete sitelib directories 
- use a better BuildRoot
- drop a redundant mkdir in %%install
- call patchlevel.h only once; rm patchlevel.bak
- update modules Sys::Syslog, Module::Load::Conditional, Module::CoreList,
    Test::Harness, Test::Simple, CGI.pm (dropping the upstreamed patch),
    File::Path (that includes our perl-5.10.0-CVE-2008-2827.patch),
    constant, Pod::Simple, Archive::Tar, Archive::Extract, File::Fetch,
    File::Temp, IPC::Cmd, Time::HiRes, Module::Build, ExtUtils::CBuilder
- standardize the patches for updating embedded modules
- work around a bug in Module::Build tests bu setting TMPDIR to a directory
    inside the source tree

C<Archive::Extract> can use either pure perl modules or command line
programs under the hood. Some of the pure perl modules (like
-C<Archive::Tar> take the entire contents of the archive into memory,
+C<Archive::Tar> and Compress::unLZMA) take the entire contents of the archive into memory,
which may not be feasible on your system. Consider setting the global
variable C<$Archive::Extract::PREFER_BIN> to C<1>, which will prefer
the use of command line programs and won't consume so much memory.
