HDirect and GHC-6.6

Here are some details on my building of HDirect with ghc-6.6, and where I am stuck.
Skipping details about deprecated libs (such as IOExts) and some name conflicts (NativeInfo), I succeeded in building the "ihc.exe", the "hdirect" and "com" libs.
I installed the "com" lib as a package on my system:

$ ghc-pkg.exe list
    [...] com-0.22, fgl-5.2, (ghc-6.6),  [...]

$ ghc-pkg.exe describe com
name: com
version: 0.22
exposed: True
exposed-modules: AutoPrim Automation ClassFactory Com ComDll
                 ComException ComPrim ComServ Connection ConnectionPoint
                 EnumInterface ExeServer HDirect Pointer PointerPrim SafeArray
                 StdDispatch StdTypes TypeLib WideString
extra-libraries: kernel32 user32 ole32 oleaut32 advapi32

From here, I tried to bootstrap the ihc compiler with the support for typelibs.
$ cd ../src
$ rm -f *.o

But the "make depend" fails : 
ghc -M -optdep-f -optdep.depend  -optdep-o -optdepo -cpp -DBEGIN_SUPPORT_TYPELIB
UPPORT_TYPELIBS='-}' -package com   -fglasgow-exts -static -fvia-C -Rghc-timing

    Could not find module `TypeLib':

I do not understand why "TypeLib" is not found, as it is included in the "com" package.
This may be a newbie's question, excuse me if it has been answered millions of time.

Sincerely yours,


PS : if I use the option in the src/Makefile, which consists in using "-i../comlib" and other flags instead of "-package com", the "make depend" works, but the following make fails as follows :

ghc -fglasgow-exts -static -fvia-C -Rghc-timing -Wall  -i../lib -L../lib -I../lib -i../comlib -lole32 -loleaut32 -ladvapi32    -c ../comlib/AutoPrim.hs -o ../comlib/AutoPrim.o -osuf o
../comlib/AutoPrim.hs:69:0: Invalid type signature

Hope this helps.
