I fixed the postgres issue (I compiled 1.2 driver there, updated to latest 2.3). I released another set of binaries in the same location:
http://acs-misc.sourceforge.net/ns_rel_beta2.html
Note: it still won't work for OpenACS 4. One: it has new version of ns_xml that breaks current OpenACS 4. See this thread: https://openacs.org/bboard/q-and-a-fetch-msg.tcl?msg_id=0002Bh&topic_id=11&topic=OpenACS
.
Two: it lacks nssha and nscache, both required for running OpenACS (I'll try to add those in the near future).
