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.
