unable to install Plack

jjmoka has asked for the wisdom of the Perl Monks concerning the following question:

I'd like to try Plack. The official site says only to do 'cpanm Task::Plack' as it couldn't end but well. But it's not my case. The is no forum to ask there. I received a new user account on a server, where perl version in 5.8.5. cpan didn't succed to intsall Plack, I thus installed cpanm (cpan App::cpanminus). It also failed. I thought it was better to update the perl distribution, so I added perlbrew and then perl 5.22.0. But with no better results.

It starts as

-> Working on Task::Plack

+tar.gz ... OK

the fails on many dependencies and ends as:

Any web discussion on Plack supposes it's installed, and anyhow the installation should come with no problems. But in a pretty fresh environment of my new server home, there is non choice to have it installed. Any suggestion on how to have it really running will be appreciated

Thanks

Learn how to read the logs. You skipped all the important parts: the first real failure can give a clue to us, not the last summary. Also, use `<code>...</code>` tags for the logs, maybe combined with a `<readme>` if they're long. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]

Ok thanks to all. Actually I already upgraded to 5.22.0.....and yes, I'll learn better how to read and post logs. Anyhow I fixed the problem. I did like that: `1. perlbrew install-cpanm 2. perlbrew switch perl-5.22.0 3. cpan 4. cpan> upgrade 5. 1 hour to say [yes] to any question 6. ~/perl5/perlbrew/bin/cpanm Plack 7. ~/perl5/perlbrew/bin/cpanm Task::Plack` [download] With not much experience I hope I just found the long way, as it is should be the standrad one, it's a mess!

I suspect that a later version of perl is needed - 5.8.5 was released in 2004, 5 years before Plack stakes its' earliest copyright claim. A user level that continues to overstate my experience :-))	[reply]
