getLinkDeps panic

I am working on a project which uses mutually recursive modules and Template Haskell. Since "ghc --make" does not seem to figure out the dependencies properly in this case (see bug #1012 (closed)) I gave Cabal's make backend a try without luck (I'm stuck again).

The compilation results in:

/usr/local/bin/ghc -package-name ForSyDe-0.1 -hide-all-packages -i -idist/build/autogen -idist/build -isrc -Idist/build -odir dist/build -hidir dist/build -stubdir dist/build -package packedstring-0.1.0.0 -package base-3.0.1.0 -package regex-posix-0.72.0.2 -package mtl-1.1.0.0 -package pretty-1.0.0.0 -package template-haskell-2.2.0.0 -O -Wall -fno-warn-name-shadowing -fno-warn-orphans -idist/build  -c src/ForSyDe/Process/SynchProc.hs -o dist/build/ForSyDe/Process/SynchProc.o  -ohi dist/build/ForSyDe/Process/SynchProc.hi

ghc-6.8.2: panic! (the 'impossible' happened)
  (GHC version 6.8.2 for i386-apple-darwin):
	getLinkDeps No iface for ForSyDe-0.1:ForSyDe.System.SysDef

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

make: *** [dist/build/ForSyDe/Process/SynchProc.o] Error 1

However, the interface file is available to ghc:

$ ls -l dist/build/ForSyDe/System/SysDef.hi
-rw-r--r--  1 fons  staff  2225  2 ene 18:13 dist/build/ForSyDe/System/SysDef.hi

Sorry, but I couldn't narrow down the problem. To reproduce it, simply download my library (http://homepage.mac.com/alfonso.acosta/.Public/ForSyDe.tgz ) and build using Cabal's make backend:

$ tar -xvzf ForSyDe.tgz; cd ForSyDe; ./Setup.hs configure; ./Setup.hs makefile; make

Curiously enough, building the library itself does not work but loading a test in ghci, works perfectly well and builds the whole library without problems:

$ cd ForSyDe/examples/ ; ghci -i../src ParAddFour.hs
GHCi, version 6.8.2: http://www.haskell.org/ghc/  :? for help
Loading package base ... linking ... done.
... (vompilation skipped)
Ok, modules loaded: ForSyDe, ParAddFour, ForSyDe.AbsentExt, Language.Haskell.TH.Lift, ForSyDe.Vector, ForSyDe.Backend, ForSyDe.Backend.Simulate, Language.Haskell.TH.TypeLib, ForSyDe.Process, ForSyDe.Process.ProcVal, ForSyDe.ForSyDeErr, ForSyDe.ForSyDeErr, ForSyDe.Netlist, ForSyDe.Process.ProcFun, ForSyDe.Process.ProcFun, Language.Haskell.TH.LiftInstances, ForSyDe.System, ForSyDe.System.SysDef, ForSyDe.System.SysDef, ForSyDe.OSharing, ForSyDe.OSharing.UDynamic, ForSyDe.System.SysFun, ForSyDe.Signal, ForSyDe.Netlist.Traverse, ForSyDe.System.Instantiate, ForSyDe.Process.SynchProc.
*ParAddFour> 

It is a major blocker for the project (I have been stuck for days). I hope you find appropiate that I tagged it as such.
