The tcptest.stp failed on most of the platforms. When trying to
compile
the script by hand it gets a number of errors:
"failed to retrieve return value location: identifier '$return'"
For
install/share/systemtap/tapset/tcp.stp:159:9
install/share/systemtap/tapset/tcp.stp:129:9
This is looking like there might be a problem with the
debuginformation for some of the kernels.

I could not reproduce any "$return" error on my boxes (ia32 & x86_64).
Looks like Bibo also had this problem earlier, not sure if he still sees
the issue, or if any resolution has been made. See the thread below.

On the other hand, I do see the tcp_test.exp fails occasionally when TCP
traffic on the test machine is really low, so the test itself may be
part of the problem. I just need to twist tcp_test.exp to send/receive
more packets when it is executed. This should reduce the number of
failure, and perhaps isolate the cases where the real "$return" errors
appear.
