#3214: "undefined reference to..." when compiling parallel code

First of all, sorry if it's not a bug in GHC, but I just don't know where
to file it.
When compiling a file that imports Control.Parallel (par), I receive the
following error:
death-star% ghc par.hs -O2
par.o: In function `s15L_info':
(.text+0xce3): undefined reference to
`__stginit_parallelzm1zi0zi0zi0_ControlziParallel_'
collect2: ld returned 1 exit status
Disabling optimizations just make things worse:
death-star% ghc par.hs -fforce-recomp
par.o: In function `r6b_info':
(.text+0x106d): undefined reference to
`parallelzm1zi0zi0zi0_ControlziParallel_par_closure'
par.o: In function `sEr_info':
(.text+0x143b): undefined reference to
`__stginit_parallelzm1zi0zi0zi0_ControlziParallel_'
par.o: In function `r6b_srt':
(.data+0x368): undefined reference to
`parallelzm1zi0zi0zi0_ControlziParallel_par_closure'
collect2: ld returned 1 exit status
Is this a bug in GHC? In ld? Any missing dependency in my distro?
I'm using Ubuntu 9.04, GHC 6.8.2 built from the repositories.
Thanks for your time.
