I would line to suggest that /usr/bin/env is used, like

 #!/usr/bin/env python
      or
 #!/usr/bin/env perl

to ensure better portability

the "#!" (a.k.a "shebang") mandates a full path, and not all
systems have perl/python/ruby/whatever in /bin.

env(1), on the other hand, is required (SUS/Posix) to live in
/usr/bin.  The point of env(1) is that it searches your PATH
for the given binary, and executes it from wherever it finds it.
