Thanks, Thomas. Linking in only libffi.a, libgmp.a, I get (for example, there are many more) missing: "_newCAF" "_base_GHCziBase_plusInt_closure" "_base_GHCziList_zzipWith_info" "_base_GHCziList_lvl5_closure" by also linking in libHSrts.a, I no longer am missing _newCAF, (and others that were missing without it) but am missing a lot of _base_GHCzi... references. I've been unable to track these down. By the way, I can't find either a libc.a or libm.a on this machine using either locate or spotlight. Is there a way to "guess" which library things are in, short of doing an nm with some appropriate option on each .a file in the Haskell lib?
