ghc 6.8.2 broken after Security Update 2008-005 (PPC) on Mac OS 10.4.11

This weekend I installed Apple's Security Update 2008-005 (PPC). This morning I discovered that ghc, ghci and runhaskell are not working. (I am certain that ghc and runhaskell were working in the last two weeks.) For instance, when compiling the simple file randil.hs (attached) I see:

ghc-6.8.2: internal error: stg_ap_pv_ret
    (GHC version 6.8.2 for powerpc_apple_darwin)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
Abort trap

Running that via ./randil.hs yields

runhaskell: waitForProcess: interrupted (Interrupted system call)

and a crash log (attached). On the other hand, a simple hello world program (attached) does compile and execute as expected.
