I tried and found if you get a fresh new codes from cvs and then 
".configure --prefix=/local/systemtap; make; make install", everything 
should be ok.

But if you first install systemtap with the default prefix, and then 
you ".configure --prefix=/local/systemtap; ... ", it will complain not 
finding tapsets and runtime, just as what Nathan saw.

The reason is because that after "./configure 
--prefix=/local/systemtap", Makefile is regenerated to have a new 
PKGDATADIR, but stap won't be regenerated, so stap still use the old 
PKGDATADIR definition.

So I tried to "make clean" after I use configure to install stap to a 
new location, then it won't have problems any more.
