Re^3: perl module installs getting really mesed up

[leocharre]

• It may also be worth looking over your cpan config...

  It may be somewhere like '/usr/lib/perl5/5.8.8/CPAN/Config.pm' .. I think maybe older CPAN was using the ~/.cpan dir or something with config- not certain about that. The default config can be overridden with ~/.cpan/CPAN/MyConfig.pm (see below)

  Try # locate CPAN | grep -i config

  Here is one of mine (/usr/lib/perl5/5.8.8/CPAN/Config.pm), in case something really different stands out..

  
  # This is CPAN.pm's systemwide configuration file. This file provides
  # defaults for users, and the values can be changed in a per-user
  # configuration file. The user-config file is being looked for as
  # ~/.cpan/CPAN/MyConfig.pm.
  
  $CPAN::Config = {
    'auto_commit' => q[1],
    'build_cache' => q[10],
    'build_dir' => q[/root/.cpan/build],
    'cache_metadata' => q[1],

  Also, I am assuming you are running as root.. look inside ~/.cpan/CPAN/MyConfig.pm, is that file there? Anything strange?

• And you did mention you looked inside ~/.bashrc and there's nothing freaky.

• Maybe also compare the test and production machines cpan configs (against each other).. and their env set variables ( with '# set' ).

• And maybe '# uname -a' on both machines, maybe check google for anything with cpan fails and that architecture.. google for = 'site:http://www.linuxquestions.org/ $architecture cpan failure' (there may be something)

(You probably already did all of this, I don't want to seem patronizing)

I have located the config and it is fairly different from the test machine. Nothing obvious jumps out. What is really clear however is that I am not even really sure what I want from the CPAN config. I mean in test at least at the moment I probably want to bang stuff in. So my action plan seems to be:
• Try installing a private 5.8 version of perl in test.
• Look at lower memory solutions like CPAN::SQLite.
• Learn treat CPAN as a friend and get to know it more intimately.
Maybe one day I will have a budget to throw at the problem, in the meantime thanks to everyone for their help.

[leocharre]

What you want from the CPAN config is that it controls your command line cpan. This is likely not where the problem is- but if the CPAN config is sufficiently f****d up, commmand line cpan won't work.

(Really? You don't see how the config file would influence the program in any way?)

[SilasTheMonk]

CPAN is a complicated module compared to what me as an end user would like it to be. Ideally I would like it not just to read my mind but predict how I would react in unusual situations. I find it frustrating when installs fail. I also have contradictory wishes. Now I think about I see it is entirely possible that I have messed up the CPAN config since: 1.) I have a poor understanding of CPAN 2.) I have not resolved my internal conflicts over how I want it to behave. So it seems at the moment I have to complete a lot of installs manually. I do not like this. However I now realize I need to study CPAN a lot more before I can solve that problem.
