I don't know if it is related, but uuid-lib's tests fail:

If you intend to take a deeper look at that issue, maybe you can take a
look at the egg's source.  You can obtain it with chicken-install or
with svn (includes VCS history):

- with chicken-install
  $ chicken-install -r uuid-lib

- with svn
  $ svn --username=anonymous --password= co

Best wishes.
