Should /usr/bin/perl be a link to /usr/local/bin/perl ?

[Yuri]

I found that many ports specify /usr/bin/perl as an interpreter. This 
comes from Linux. Examples: valgrind-snapshot, windowmaker, enscript-a4, 
a2ps, svgalib
/usr/bin/perl isn't installed by perl port.

There are several solutions, in the order of increasing complexity of 
solution:
1. Install the link /usr/bin/perl (hackish, but it will fix many broken 
ports in one shot)
2. Make a package scripts check for interpreter and break the install of 
offending packages
3. Fix all offending packages

Which solution should be preferred in your opinion?
