BTW, systemtap 0.9.5 is now available as part of the standard Fedora 10
package set, so you don't have to install any nonstandard software
anymore.  I've checked, and 0.9.5 appears to "just work" with our
CVS HEAD.  You need these packages:

$ rpm -qa | grep systemtap
systemtap-sdt-devel-0.9.5-1.fc10.x86_64
systemtap-runtime-0.9.5-1.fc10.x86_64
systemtap-0.9.5-1.fc10.x86_64

Then configure --enable-dtrace, and away you go.
