unix package doesnt load in ghci on freebsd/amd64

[newsham]

When loading the "unix" package in ghci, the interpreter gives a link error:

$ ghci -package unix
GHCi, version 6.8.2: http://www.haskell.org/ghc/  :? for help
Loading package base ... linking ... done.
Loading package old-locale-1.0.0.0 ... linking ... done.

Loading package unix-2.3.0.0 ... ghc-6.8.2: can't load .so/.DLL for: util (/usr/lib/libutil.so: Undefined symbol "__mb_sb_limit")

As noted above this is ghc-6.8.2. I built from sources. My machine is:

FreeBSD hpsux 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sat Mar  8 14:07:11 HST 2008     root@hpsux:/usr/obj/usr/src/sys/GENERIC  amd64

Based on a quick google, it looks like this is a FreeBSD libc thing. Did you build against the same libc you are running?

I cannot reproduce this on FreeBSD 7.1-PRERELEASE amd64 using lang/ghc. Please update your ghc using the FreeBSD port and retry.
