Rebuild perl instmodsh command index

Question

Lang/Env:Perl 
Version: 5.8.8
OS: CentOS 5.3

How does instmodsh works exactly? How it create indexes? Is there any way to rebuild these indexes ? Is there any other tool available for managing modules ?

When I am using "instmodsh" for below module it is showing following output: XML::NamespaceSupport XML::XML::NamespaceSupport

Why is so ? It is installed only once and single version only. Any Help would be appreciated.

Answer 1

Another part of the question "Is there any other tool available for managing modules ?" One tool is available:

perlmod

It provides features like installation of modules, remove, print version, files of a modules etc.

You can get this tool at http://www.seofreetools.net/download/scripts/perlmod/perlmod.v.1.1.0.tar.gz

and rest of the information.
