ruby update:

* xrefresh server on Linux (only paths config option is honored)
* sup can be started without hacks now :)
* rubygems update 1.3.5
* fix handling of /bin/* ruby scripts
* only recognize runtime dependencies when creating nix derivations.
  Some development dependencies are no longer available.
* make ruby lib ffy compile by using NIX_POST_EXTRACT_FILES_HOOK
* update rubygems patch: Even if there is a missing dep create attr
  item. Maybe this missing source can be fixed manually.
