Perl 5.14 removed Switch which means that Rockbox will no longer build
with the current release of Perl. The patch replaces Switch
with given/when which was introduced in Perl 5.10.0.
Debian stable has 5.10.1, cygwin 1.7 has 5.10.1 and Mac OSX 10.6 comes
with 5.10.0. I'm not sure what version older versions of OSX come with,
but newer versions are apparently available from Macports.
