Perlbrew a 64-bit Perl on Linode

For some reason, even the 64-bit kernel on my Linode wasn't sufficient for perlbrew to generate a 64-bit Perl. I was able to get one by doing:

perlbrew install 5.20.0 --64int

which resolved the problem I was having trying to install Minion with cpanm, namely the error "Perl with support for quads is required!" (from this bit of code, thanks mst on undernet #perl)
