Building error for latest stap tree

[Wenji Huang]

Hi,

I got building error for latest stap tree(commit 
46a8c85fde5ba9bcf4fa55e8f435959af4d32fea).

[wjhuang@EL5U2-64bits ~]$ cat /tmp/error
certutil: self-signing a cert request is not supported.
certutil:  unable to open "ssl/server/stap-server.cert" for reading 
(-5950, 2).
Cannot find certificate file ssl/server/stap-server.cert

And for EL4,
	certutil: command not found.
Seems no nss-tools rpm available. I tried yum or up2date, but
couldn't find nss-tools or certuils.

Can we have option to enable/disable it, like
./configure --disable-stap-sever

Regards,
Wenji
