My .02 cents worth:

From what I've seen in this thread I guess I am about the only
supporter of your idea, here is my justification for supporting

I think ALL ports should be restricted to /usr/local or /usr/X11R6,
seems that is the way things are anyways, why should perl be an 

There is an obvious  safety bonus if ports (including perl) are 
restricted,  for one you can mount /usr read only 
with  /var /usr/local /usr/X11R6 /tmp writable for protection of the 
basic system. This way no matter what, as long as your hardware holds 
out you should never loose the basic operating system.

With perl writing symlinks to /usr/bin you have to change the mount from 
ro to rw when you install perl, then change it back,  while that isn't 
very difficult, it is still annoying, and just a matter of time before 
you forget and leave /usr writable.  

There was another thread very recently about a one line
script that replaces words in all files from a given directory, from 
that thread how hard would it be for folks to do  something like:

find / -type f -name "*.pl" | xargs grep -l '/usr/bin/perl' |  xargs sed  
-i '' -e 's|/usr/bin/perl|/usr/local/bin/perl|g'

( I have no idea if the above script works, it is just an example...)

It just doesn't seem that big of a deal to change /usr/bin/perl to
/usr/local/bin/perl but then again 5.3 is supposed to be STABLE
so I'll still be happy if this is implemented only in CURRENT.

Well that's my .02 cents worth...


ps. I dropped all of the cross posting!
