[plt-scheme] SrPersist Sources (Linux)

I'm trying to install SchemeQL on my Gentoo Linux, but I'm having
some troubles on installing srpersist. I found the srpersist
sources on the server, but it seems that if I setup-plt those,
it doesn't do much... After installing I have a srpersist folder
with some file etc, but schemeql is still errorring out because
he misses the srpmain.ss file, that should be located in private
(where there is only a sigs file)

Any ideas on how to correctly install the sources?

Greetz.
