That suggests to me that dyninst was not linked quite right, it's
missing -ldwarf.  See "ldd /usr/lib/libsymtabAPI.so.8.0" - it should
list some libdwarf.so file.

To fix that, could try rebuilding dyninst more correctly, or adding
-ldwarf to the systemtap stapdyn/Makefile stapdyn_LDADD line, or
perhaps using 
% env LD_PRELOAD=/usr/lib/libdwarf.so.something stap
