Unclear as to problem: Tried to register 'Types', but says can't due to unrelated module.

I got an error:
Dist E/EB/EBUSBOOM/Net-ICal-0.11.tar.gz, current version undef has been 
uploaded by EBUSBOOM. Please contact EBUSBOOM or choose a different 
namespace.

I pulled down Net-ICal -- and there is nothing named Types\* in the 
distribution.

So why would it conflict?
