deployments for git-instaweb.

I probably need a little help here to figure out how to make this
"portable". I've modified Makefile, but what when configure is
called by the end user instead of relying on this streamline
Makefile? I need some hints about where to look to make this
patch more robust regarding this.

Any suggestion is welcome, of course.
