I think he might be talking about this, from the "Installation Section" of the Scoop documentation:
"Before you even start, make sure that you can
- Alter your web server's core configuration file
- Stop and start the web server
- Install programs
and check for your OS in section 2.7, System-specific notes for any special instructions.
Many hosting companies don't allow this kind of control, but without it it's impossible to install Scoop. (Scoop is not a cgi script that you can just drop into your cgi-bin directory!) "
It also seems to require mod_perl.
