Further note on this. I since tried the auto_path feature by putting
my library tapset in
tapsets/PATH/my/path/to/postgres
and used
stap -I `pwd`/tapsets/ test.stp
but had exactly the same issues. A look at the code suggests that the
auto_path feature, like the PATH search etc, is only effective for
probes, not for @var and @cast .
