Getting pkgmanager to work

[Petr Janda]

So I decided to give this a try. Installed pkgsrc-wip and pkgmanager and 
its dependencies. I run pkgmanager and get this:

/usr/pkg/bin/pkgmanager: @PREFIX@/bin/clisp: not found
I changed the prefix manually in the file to /usr/pkg and then got an 
error complaining about a missing file called packages.clisp, i did a 
locate on this file and it turned out theres no such file on my system. 
Where is the PREFIX value taken from? What to do to get this working?
