No, that is not what I meant.

Invocation of perl _in_ scripts can be controlled by user's
PATH, but #! cannot be.  As Merlyn says 'env' is a nice hack,
but we configure the scripts we install to have #!  pointing at
the right interpreter as a more cleaner (than using 'env', that
is) workaround anyway, so #! pointing at PERL_PATH and scripts
relying on user's $PATH would be the right thing to do.
