SLES of some level
According to the openSUSE repos, SLES 11 uses 5.10.0. I'm not sure if that's entirely accurate, though.
I advise doing this too. You can also use something like App::PerlBrew(although unfortunately that doesn't work for me for some reason), or just download your favourite Perl version from CPAN and compile that.
I keep telling myself to use that, but I'd probably end up having to reinstall many of the modules(especially the XS ones), and that takes too much time.
