Hi,

I am really confused. I am trying to install the POpen4 gem and it seems  
that it is not in any repository, but it is. See the following:

C:\Documents and Settings\César\Mis  
documentos\NetBeansProjects\music\>gem list -  
r popen

\*\*\* REMOTE GEMS \*\*\*

POpen4 (0.1.1)

C:\Documents and Settings\César\Mis  
documentos\NetBeansProjects\music\>gem instal  
l POpen4  
ERROR: could not find gem POpen4 locally or in a repository

Where is the problem?
