upstream is not a class method of AptPkg::Version, but requires an
object of that type.
use AptPkg::Config '$_config';
use AptPkg::System '$_system';
use AptPkg::Version;
$_config->init;
$_system = $_config->system;
my $vs = $_system->versioning;
print $vs->upstream("1-2"), "\n";
See also /usr/share/doc/libapt-pkg-perl/examples/apt-version .
Shouldn't SEGV though, I'll change the code to either return an error
for AptPkg::Version->upstream, or to automagically create one.
