[perl #69302] installperl does not delete files before copying

In Snow Leopard, Apple replaced the scripts that come with perl  
(pod2html, perlbug, etc.) with wrappers that delegate to the script  
with the version number tacked on the end (pod2html5.8.9 or  
pod2html5.10.0 [Snow Leopard comes with two versions of perl]). All  
these wrappers are actually hard links to the same file.

I was trying to install 5.10.1 over the system perl (with -Dprefix=/ 
usr), and, since the scripts already installed are all the same file,  
psed ended up being installed with a dozen different names, it being  
the last script to be installed.

Shouldn’t installperl be unlinking files if they already exist?
