Re: GHCi bug - the impossible happened loading FranTk with ghc-6.0 on Win32
I tidied up this aspect of TclHaskell / FranTk as part of a Galois project a while ago. Attached are the as-is changes needed to avoid being dependent on RTS internals & stop doing a busy wait.

It looks like you're trying to do a parallel make (make -jN). We have some known problems in this area. I'm not sure exactly where the -j flag would be coming from, but I'm fairly sure it's not the default. Check your /etc/make.conf. The port should probably turn off -j if it finds it.

RE: GHCi bug - the impossible happened loading FranTk with ghc-6.0 on Win32
Simon The underlying problem is that no one is maintaining FranTk at the moment. Perhaps you'd like to? Anyway, FranTk seems to use an un-documented (and therefore unreliable) hook into GHC's RTS. When you use GHCi to load systems that link to RTS hooks, the dynamic linker's symbol table must be initialised to include those symbols. So the 'solution' here is to add 'run_queue_hd' to the RTS_SYMBOLS in ghc/rts/Linker.c. You'll need to build GHC from source do to this. Longer term, it'd be a good plan to see just what FranTk wants to know here, and what API the RTS should expose to support it.
