Three things to try:

First, try shifting things around in the bundle list, to put some of the lower-level modules first before you get to the larger ones that use those modules.

Second, eliminate core modules from your bundle file. Things like IO::Socket are bundled *with* Perl, so if you're telling it to install it, it may be confused and try to install it separately by downloading the parent package that it's installed under (e.g perl_5.6).

Third, did you let it finish? Perhaps it is keeping track of dependencies and would have tried loading them after the bundle file had been exhausted? Bundle behavior seems to be inconsistent sometimes from what I've read.
