Head GHCi fails to load package unix

[wld]

GHC built from Darcs head fails to load the package 'unix'.


$ ./ghc-inplace --interactive -package unix

Loading package base-1.0 ... linking ... done.
Loading package unix-1.0 ... linking ... ghc-6.5:
/home/wld/test/fp/libraries/unix/HSunix.o: unknown symbol `lstat'
ghc-6.5: unable to load package `unix-1.0'


The small test of using 'lstat' compiles and links fine
with 'ghc-inplace --make'.


import System.Posix.Files
main = getSymbolicLinkStatus "Test.hs" >>= return . linkCount >>= print


My environment:
  Linux 2.6.15
  gcc 4.0
  glibc 2.3.5
