The problem is due to shared libraries. Need to set up so looks for
shared 
libraries in when running the tests. Below demonstrates the problem.

$ 
LD_LIBRARY_PATH=/home/wcohen/systemtap_write/obj/lib-elfutils:/home/wcoh
en/systemtap_write/obj/lib-elfutils/systemtap:$LD_LIBRARY_PATH 
  ./stap ../src/testsuite/systemtap.samples/tcptest.stp

Okay the following works:

$ LD_LIBRARY_PATH=/home/wcohen/systemtap_write/intall2/lib/systemtap
./stap 
../src/testsuite/systemtap.samples/tcptest.stp

This does not work:

$  ./stap ../src/testsuite/systemtap.samples/tcptest.stp semantic error:
failed 
to retrieve return value location: identifier '$return' at

Pass 2: analysis failed.  Try again with more '-v' (verbose) options.
