Today I was trying to install a old perl version(I am a novice at perl programming book uses an older version) in a self contained environment with perlbrew. Somehow in doing so I mistakenly modified something on my distros core_perl/vendor_perl and I am not sure what I did.

That being said I know the problem lies with permissions. For example if I use perldoc as my normal user I get the following message

However if I do the same as root then perldoc works.

All my usr binary directories are world readable and executable so I do not know why perldoc can not find its module. I also reinstalled all installed perl packages and that did not help. I am not sure what to do to fix this because frankly I do not know what I did wrong to cause this problem in the first place. IF anyone can lead me in the correct direction would be much appreciated.

Hi,

leave the version of Perl as it is and declare which old version to use in your scripts. It's described here http://stackoverflow.com/questions/1...of-perl-to-use
