If you are using Project Builder to build RoachesView, go to the 
Builder menu and choose install as the target before building.

To build RoachesView from the command line, type

/bin/make install

(Ignore the warning, "Timing.m:151: warning: ANSI C forbids newline in 
string constant.")

In either case you should find a new bundle,

RoachesView.BackModule

in 

~/Library/BackSpaceViews

BackSpace modules obey a different naming convention than most bundles.
The after_install target in Makefile.postamble is takes care of this.
