[Haskell] Odd link error

[Thomas Davie]

Hi,
   I'm getting an odd link error trying to build with ghc 6.2.2 on OS  
X, and can't figure out what's going on. From it's form, I assume  
that the symbol is part of the runtime, but greping the files in /usr/ 
local/lib/ghc-6.2.2 returns no results.

dhcp2934:~/Documents/hat tatd2$ make
cd src/hattools;      make HC=ghc install
hmake -hc=ghc -I. -I/Users/tatd2/Documents/hat/include -fglasgow-exts

Has anyone got any idea what's going on?
