Then you would have nobody but yourself to blame. >From the Perl documentation: It may seem obvious to say, but Perl is useful only when users can easily find it. When possible, it's good for both /usr/bin/perl and /usr/local/bin/perl to be symlinks to the actual binary. If that can't be done, system administrators are strongly encouraged to put (symlinks to) perl and its accompanying utilities, such as perldoc, into a directory typically found along a user's PATH, or in another obvious and convenient place. In this documentation, #!/usr/bin/perl on the first line of the script will stand in for whatever method works on your system. > > I'd say let the ports patch the right location at install time and if > they break after upgrading both perl and the port, they deserve no better. And what about all the scripts that administrators and users write that are not part of any port? Scripts that were written according to the de-facto standard that having '#!/usr/bin/perl' on the first line of the script will work correctly. No, the proposed change is a bad idea that will create lots of problems for very little gain. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
