Can we make the caches sharable by encoding variables like
$Config{use64bitint} and $Storable::VERSION into $cache_path?

Something like this (untested):

	use Config;

	my $cache_path = "$ENV{GIT_DIR}/svn/.caches/";
	$cache_path .= "$Config{use64bitint}.$Storable::VERSION/";

We'll blow everybody's cache away once during the git-svn upgrade, but
in the future people will be able to share the same working tree between
different versions of perl/Storable/whatnot without needing extra code
to detect croaks, different build options, and nuking each other's
caches.
