Hey All, 
As of installing xcode 4 earlier today, 

i'm getting errors of the form 
ld: library not found for -lcrt1.10.5.o
collect2: ld returned 1 exit status

for any haskell code that invokes ld in its cabal install process.  
1) is this related to some problem in xcode / what the haskell code defaults to linking to?
2) is this something completely unrelated?

thanks!
