I disagree. /usr/bin/perl5.12 makes upgrading a great deal more difficult in the future (since everything that uses perl such as intrd(1M) would have to be modified) and /usr/bin/perl makes demands of the distributions that the canonical perl be the required system perl, ie they can't deliver their own newer/older perl with different features as the canonical perl.

Pointing to /usr/perl5/bin/perl is a good compromise IMO of having a central unversioned place to find system perl, without forcing anyone who doesn't want to to use potentially outdated technology
