Bug or "Feature" Can not package manager gui with non-connected box

[Harry Smith]

I am setting up a system in an area where I can not connect to the 
Internet.  I chose a minimal install from the GUI, i.e. don't make it 
any of the pre-defined options.  I was planning to return after the 
install and add the packages I needed.

The install finished,  when I tried to add packages it failed 
immediately.    I can add the rpms manually.

So is this a bug or feature in FC 5.
