Yes, this bug is an unforeseen consequence of recent changes related
to error messages.  I'll fix it properly soon, but in the meantime,
here's a workaround.

Assuming you have already built all the normal profiling components,
do the following:

  ( cd src/prelude/PreludeIO;
    ../../../script/nhc98 -c -p +CTS -lib -CTS DErrNo.hs \
        -o ../../../targets/`harch`/objp/prelude/PreludeIO/DErrNo.o )
  ( cd src/prelude;
    make CFG=p install )

As you can see, only one file needs to be rebuilt: the all-important
difference is the compile-time argument  +CTS -lib -CTS.  Then the
second step recreates the profiling prelude archive.

Hope this helps,
    Malcolm
