Did you add the new source files to _<foo>_la_SOURCES in Makefile.am?

Are you trying to run qa_howto.py from the command line without using
"make check"?  Try running "make check" instead.  Running from the
command line will use the installed version of the libraries,
generally not what you want.  "make check" and run_tests adjust a
bunch of environment variables in order to run the non-installed code
from the build tree.
