[Bioperl-l] help on installation of bioperl in slave nodes.

[Chris Dagdigian]

Your problem is simple and has nothing to do with bioperl.

Simply put your, slave nodes can't get to the internet. This means that 
they can't find CPAN to download the modules.

Some options include:

1. configure your cluster so the nodes can talk to the internet. Many 
clusters I work on use some sort of NAT or HTTP proxy for exactly this 
purpose. Most clusters also have a mechanism for taking changes that 
were made to one node and replicating them out cluster-wide so you only 
need to really install bioperl once on one machine.

2. If you can't get the nodes to see the internet you can manually 
download all of the needed perl modules and  install them on one or more 
slave nodes. In fact if you used the CPAN method on your cluster head 
node the packaged code may still be laying around in your .cpan/
folder

But when I get into the slave nodes and use the same method to install the Bundle, it did not succeed. The error message is about the connection problem. Can anybody give me some hints on this issue?
