Description of problem:

The `nppm list -g` complains about a ton of missed dependencies when using npm installed out-of-box on a SL6.5 with nodejs from EPEL.

Version-Release number of selected component (if applicable):

nodejs-inherits-2.0.0-4.el6.noarch
npm-1.3.6-5.el6.noarch
nodejs-0.10.28-1.el6.x86_64

How reproducible:

# yum install -y npm
# npm list -g

Actual results:

[root@mrsa ~]# npm list -g

Please note that this is a fresh installation, so I don't suppose bug #997978 is relevant.

Stuff can be fixed by these two steps:

[root@mrsa ~]# rm -rf /usr/lib/node_modules/inherits
[root@mrsa ~]# mv /usr/lib/node_modules/inherits@2 /usr/lib/node_modules/inherits

Anyway, I'm not familiar with now Node.js is supposed to be deployed or the way how modules are handled, but I suspect that at least some component chokes when the module names look like inherits@2. Simply cp-ing that directory to the place where the symlink was did not fix the output; `npm list -g` still complained about an invalid name of "inherits@2":

[root@mrsa ~]# npm list -g
