the author of wasysym, Axel Kielhorn, has been aware of
the problem. Look at the package documentation in
wasysym.pdf. I am not sure whether I understand it entirely,
but either
   \usepackage[integrals]{wasysym}
or
   \usepackage[nointegrals]{wasysym}
should yield compatibility with amsmath, and the
documentation explains which package option yields
which way of dealing with amsmath, as Barbara has
discussed with \let (see the `Integrals' section of the
documentation as well as the `Changes' section
concluding wasysym.pdf -- which has tiny 3 pages).
So solving the problem seems to be possible with
"pure" LaTeX code (at least if one doesn't want to
use both styles of integral symbols in the same
document).

-- Maybe zac has not used wasysym version 2.0
-- which introduced these package options --
and neither has seen its documentation
(dating from 2003/10/30).

Hope this helps,
   Uwe.
