- Ubuntu Hardy with erlang 12b3 from Intrepid (1:12.b.3-dfsg-1ubuntu1) (*)
- git HEAD aebdb31001126dab6b579b8cc2e605ef7ec499c6 (**)
- Builds and installs without errors
- But drops HTTP connections on the floor :-(

$ telnet localhost 5984
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET / HTTP/1.0

Connection closed by foreign host.
$ 

- To me the backtrace suggests a problem with re:split, but it mentions
  oauth in the same breath

commit aebdb31001126dab6b579b8cc2e605ef7ec499c6

    The RSA SHA1 Oauth module was breaking trunk for older versions of the Erlang
    VM. Since we don't actually use it, I'm removing it from the build until
    we add a ./conifgure option or we update our Erlang version requirement.
