in reply to Re^2: Uninstalling / installing perl
in thread Uninstalling / installing perl

Hi sirsir,

My advice was based on the fact that your OS may have dependancies on the version of Perl that it is installed as part of the OS distribution. Changing this version of Perl may result in some system tools failing to work properly.

However I was not trying to tell you what to do, after all it is your system, you can obviously do with it what you wish. I was simply trying to point out a potential problem that may occur based on your course of action.

Did the make install throw any errors/warnings? Out of interest, what does perl -V show.

    make install worked fine I think, I ran it with the prefix as /opt/perl. perl -v looks like this: This is perl, v5.8.8 built for i686-linux-thread-multi Copyright 1987-2006, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.

      Hi sirsir,

      To answer your question 'so am I screwed' (which I noticed you have replaced with the information above), you can simply restore what you have deleted from your last good system backup.

      Annoying isn't it? At my first computer programming job, I realised that I had made a mistake and deleted a file I had been working on (some Allaire ColdFusion nonsense I believe:). I wasted no time in telling my co workers of my mistake, at which point one of them replied:

      "Thats ok, just restore it from backup"

      I had no backup to restore from. Lesson learned.

      On a serious note, is the current state of play that you do not have /usr/bin/perl (and /usr/lib/perl5/). If so I would be concerned about system stability.

      I think marto was asking for perl -V. You've provided perl -v which is not quite as informative. Also, note that the @INC you provided (and possibly the perl -v also) is for the perl in /usr, not the perl in /opt.

      Anyway, I think it's a good idea to have installed the second build, and you should use it for your personal stuff, rather than the perl that's in /usr. Are there now any problems with the perl that's in /opt ?

      Cheers,
      Rob
