I have the same problem building directly from the 2.0.5 tar file (from the project page) on OS X 10.7.3

...
  SNARF  posix.doc
  SNARF  net_db.doc
  SNARF  socket.doc
  SNARF  regex-posix.doc
  GEN    guile-procedures.texi
guile: uncaught throw to unbound-variable: (#f Unbound variable: ~S (id-15978) #
f)                                                                             
Cannot exit gracefully when init is in progress; aborting.

I get similar results with 2.0.2.

Let me know if you need the full output.
