That is not what I said (but, no, they are not necessarily buggy depending on why the they don't heed PREFIX/LOCALBASE.)

It might be the canonic way and it might even be the best way, but it is not the standard way. Older versions of perlrun(1) (like the one included in FreeBSD 4.x) does not even mention /usr/bin/env so don't expect too many scripts to use it (and the context in which 'env' is mentioned is handling OS-specific limitations of the #! mechanism.) perlrun(1) does however say that "When possible, it's good for both /usr/bin/perl and /usr/local/bin/perl to be symlinks to the actual binary." -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
