Yes. Sorry, a late, too quick "easy fix" on my part. I just ASSumed  
people using late-model Chicken would have these.

(FWIW, the above is very recent so it shouldn't effect too many  
people. I will post updates today of everything.)

As for the ordering of needed eggs:

1) For the time being I suggest people watch the messages from setup  
for "egg not installed". If they see one stop the build, setup the  
egg separately, & restart the previous build.

2) Assume the (needs ...) list a partial order. Then recursively  
extend each reference w/ its' references, until bottom. Then the list  
would be a topological sort of the dependencies. Setup the resulting  
list in order.

baz
        (needs foo bar)

foo
        (needs abc nbc)

abc

nbc

bar

=>

        (needs abc nbc foo bar)
