I am not sure, what's wrong in your installation. Most probably, there are earlier errors after restart of the server. To ease communication and version management, i have added s5 to cvs head and set the dependency to xowiki 0.70 and xotcl-core 0.70.
Note that there is no head version of XOTCL, but just a head-version of xotcl-core. XOTcl is a C-level Tcl extension, currently released in version 1.5.4.
