Re: [Chicken-users] Changes to Svnwiki's extensions system coming

[Ivan Raikov]

  By the way, I did a fresh installation of svnwiki today, and it
appears that any extensions using SRFI-40 streams no longer work. For
example, the svnwiki-post-commit script bombs with the error below
when trying the commit the Nameless Wiki for the first time. Any
references to the SRFI-40 procedures like stream-cons, stream-delay
and so on, result in the unbound variable error. Any ideas what's
going on?
