DomTool source code is, at places, HCoop and OpenAFS-specific. Here's a documented procedure for setting up DomTool on non-HCoop machines and without using AFS.
Set up /etc/domtool (or specifically, the SSL CA in there) accoridng to DomTool/SslProcedures
Build and install the DomTool suite as explained in DomTool/Building and DomTool/Installation. (When creating user 'domtool', you can choose /home/domtool as the home directory)
- Edit /etc/init.d/domtool-* to replace shebang line /usr/bin/pagsh.openafs with /bin/sh (or /bin/bash)
