 I have installed Msys2 on Windows. In Msys2 I have installed Emacs, which
 I start with a custom cmd script with following environment variables set:

 {{{
 SET PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH%

 set XDG_DATA_DIRS=c:/msys64/mingw64/share
 set PKG_CONFIG_PATH=c:/msys64/mingw64/lib/pkgconfig
 set INCLUDE=c:/msys64/mingw64/include
 }}}

 The haskell I have is from Full Haskell Platform,
 https://haskell.org/platform/download/8.2.1/HaskellPlatform-8.2.1-full-
 x86_64-setup.exe

 Then I started eshell which I used to invoke this command:

 {{{
 cabal install gi-gtk
 }}}

 Which after a while gave me following error.

 {{{

   You are in a maze of twisty little passages, all alike.
   While forcing the thunk for TyThing Layout
   which was lazily initialized by initIfaceCheck typecheckLoop,
   I tried to tie the knot, but I couldn't find Layout
   in the current type environment.
   If you are developing GHC, please read Note [Tying the knot]
   and Note [Type-checking inside the knot].
   Consider rebuilding GHC with profiling for a better stack trace.
