Thanks for the report. stapio gets staprun through:
const char *staprun = getenv ("SYSTEMTAP_STAPRUN") ?: BINDIR "/staprun";
So, you can also work around it by setting SYSTEMTAP_STAPRUN to your
local staprun. But BINDIR should default to '${exec_prefix}/bin' unless
you configure --bindir=/something/else. I am not sure how it could have
been set to /usr/sbin in your case. Maybe config.log gives a hint how
bindir was set?

The NSS dependency is only needed for the client/server mode. It would
be good to have a configure --disable-stap-sever for those that don't
need it (or disable building it automagically when NSS isn't found).
