[Haskell-cafe] foreign import unsupported in GHCi on amd64?

is foreign import expected to work when using GHCi (ghc 6.4.1) on an amd64 
linux platform?

I'm just (attempting) to play around with some code (Oleg et. al.'s Zipper FS) 
that has the following lines in it:
ZFS/ZFS.hs:522:foreign import ccall "unistd.h select" c_select
ZFS/ZFS.hs:573:foreign import ccall "fcntl.h fcntl" fcntl

and I get:
Compiling ZFS              ( ZFS.hs, interpreted )
ghc-6.4.1: foreign import is not implemented for GHCi on this platform.

Ticket 290 ( http://cvs.haskell.org/trac/ghc/ticket/290 ) seems to imply the 
foreign import wrappers work in ghc 6.4.
