That seems to have been the case for quite a while now; last I heard it was suppose to be moving to pclinuxosusers.com, but it hadn't made it there last I checked.
I added the following notice to the How-to that is stickied in this section:
EDIT: The above wiki was relocated to http://www.pclinuxosusers.com/doku/doku.php/rpm-how-to:intro, but it seems to have gone missing! Until it returns, the Tiny-Me how-to that it was based upon is still available here: http://tinymelinux.com/doku.php/build-rpms:intro
That is the how-to that started our packaging wiki.. ours had quite a bit of extra information added to it, but the key info is still there.
