Looks like a patch conflict ..Check /var/sadm/patch and see if this patch 108875-07 is present, if you have a later patch than that then you might run into the above problem ..

Actually it seems to be a result of the infamous iPS bug where if you install the Portal Server in a directory that exceeds 15 characters, iPS results in an error. Is that fixed in some version? And, how does that even mange to occur? That "bug" is so Microsoft.
