[elrepo] SystemTap

[Martin Ichilevici de Oliveira]

Hello,

I'm running CentOS 7 with kernel 3.16.3-1.el7.elrepo.x86_64 and I'm
trying to use SystemTap.

I already have it installed (unfortunately I don't remember where it
came from, either from a rpm or from stock), but it crashes when I try
to run the "Hello World" from the tutorials [1]. stap-prep says I need
some packages but fails to find them.

What can I do?

$ stap --version
Systemtap translator/driver (version 2.4/0.158, rpm 2.4-14.el7)
