But I don't think the existing warning will help you in this case. On any modern UNIX-like system, there will almost certainly be a /usr/bin/perl already present. So any attempt to install another perl anywhere, (under your home directory, under /usr/local, etc) will elicit the warning that /usr/bin/perl already exists, which we probably knew anyway. If you're trying to install perl as /usr/bin/perl and that already exists, then presumably you *won't* get that warning, so the warning is only helpful in the sense that you're on-ball enough to spot its absence. -- You're only as old as you look.Thread Previous | Thread Next
