One way is to use #!/usr/bin/env perl which takes the first perl binary found in the $PATH environment variable. Then you have to tweak $PATH to point to the correct perl first on each platform.

    env is generally fine, but note that in this case you can't pass any arguments on the shebang line, because most kernels do split/pass everything after env as one argument.  For example 

    #!/usr/bin/env perl -w

    would produce (on Linux)

/usr/bin/env: perl -w: No such file or directory

      Good point! particularily on a web server (as per the OP), where you want taint checks: 

      !#/usr/bin/perl -T

    Thank you so much for that moritz. I've often wondered what env was for - its manpage does not do it justice. I'd given up trying to get bash to just run the perl it finds in $PATH.
