OK SimonM helped me past this. Just for your info * The code generator does not actually mention stg_gc_ut; that is in commented-out code.
* TH was loading HSsyb-0.3.7.o, which was an old .o file created back in August. I'd just installed syb, but cabal had created libHSsyb-0.3.7.a. Sadly TH ignored the new .a and took the old .o. Solution: delete the out of date .o file.
