Re: How do you run Perl on _your

Personally, my main Perl is a recent build that I complied myself and keep in /opt (sh Configure -de -Dprefix='/opt/perl5.xx'). That way, I can install CPAN modules into it without the worry of messing up the system Perl, and the modules are in the same directory tree as Perl itself, so I generally don't have to worry about version mismatches. Additionally, when I need a specific Perl version, I use perlbrew, which basically has the same effect of a self-contained Perl, except its environment variables can be applied temporarily. Otherwise, I agree with Fletch to stay away from the system Perl and instead use #!/usr/bin/env perl and PATH to point your scripts at whatever Perl you like. If you do want to install modules into the system Perl, use the system's package manager to do that (though that might not provide all CPAN modules or the latest versions) - I do this on older Raspberry Pis because compiling things there is very slow.

I use perlbrew, which basically has the same effect of a self-contained Perl, except its environment variables can be applied temporarily. You can use a perlbrew-installed perl in exactly the same way you'd use a self-compiled perl. perlbrew just makes it easier to install (by fetching it for you and applying patches needed to compile older versions) and to use (it can adjust your PATH for you). So I don't get why you don't always use perlbrew.	[reply]
