While I don't know anything about buildout, pyramid-tm is the
normalised version of pyramid_tm - see
https://www.python.org/dev/peps/pep-0503/#normalized-names

Your two setups may be behaving differently regarding normalisation
(I'd suspect the older version wasn't normalising correctly - it's a
relatively new change).
