I can't reproduce this problem.  With a minimal emacs config started
with -Q, and loading the attached init.el file (you'll have to update
the paths to work with your system).

I'm able to execute the following Org-mode file returning a table of
results as expected (although I have to execute it twice, presumably to
clear out some cruft at the beginning of the haskell session).
