after experimenting by just naively moving the old Developer directory back to its original location preceding the installation of xcode 4, everything builds properly now.

still, this is not a reasonable long term solution. Any ideas about how this might be fixed?

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!
