No, the two are only similar in the programs they provide, but we use
libraries that are only in elfutils (especially libdw).

Ok, when using "--with-elfutils" it should build and install private
copies of those elfutils libraries.  Are they successfully installed in
$libdir/systemtap/ ?

This is clearly picking up the system's older version of elfutils, which
lacks the necessary symbols you built against.  So after you verify that
stap's private elfutils installed correctly, please check if "eu-readelf
-d stap" contains the right RPATH/RUNPATH.

It might also be an issue if the prefix you chose was a relative path.
I'm not sure if we translate that to a full path at build time.
