Portable line shebang

Question

#!/usr/bin/perl

This is a shebang line for a lot of the scripts I have been writing lately.

Hard coding the binary path seems like it can create some problems. For example, if one of my users has Perl installed in / something _else / bin, then they will have to change all shebangs.

I saw some tools that automatically replace shebangs, but I am wondering if there is anything simpler.
