--- Comment #1 from David Smith <dsmith at redhat dot com> ---
Here's some additional information.

The error messages starting with '--SERIOUS--' and '--FATAL--' are coming from
dyninst instelf, not from stapdyn. Specifically the messages are coming from
the call to patch.processCreate() in mutator::create_process().

It also doesn't seem to matter if you specify the path to the dyninst RT
library (instead of letting stapdyn guess it):

====
DYNINSTAPI_RT_LIB=/usr/lib64/dyninst/libdyninstAPI_RT.so stapdyn -v
/home/dsmith/.systemtap/cache/55/stap_550473d97fe423f6c58bcbdf4e19de73_1121.so
-c 'ldconfig --help'
--SERIOUS-- #101: Runtime library /usr/lib64/dyninst/libdyninstAPI_RT.a does
not exist or cannot be accessed!
--FATAL-- #68: Dyninst was unable to create the specified process
--FATAL-- #68: create process failed bootstrap
stapdyn: ERROR: Couldn't create the target process
