Dear Informatics... please use your personal name if at all possible? Is there a real need to hide your identity?
Please read my page at:
http://www.xc.org/jonathan/openacs/whichfilesdoineed.html
which links to the currently recommended set of RPMs. The particular one you referred to was fixed some time ago, I believe, which changed its release number from -1 to -2.
That page really should be online... I can access it from here in the UK, and it is hosted in the USA.
