Hello libr, i think it's appropriate place to complain about Cabal? situation: ghc 6.4.2 (2006.06.09) with built-in Cabal. i install package with the following dependencies: Build-Depends: base, ArrayRef==0.1, fps>=0.7, template-haskell there are ArrayRef 0.1 (hidden) and ArrayRef 0.1.1 (exposed) installed Cabal correctly selects ArrayRef 0.1 when building the lib. but on installation it makes the following trick: Registering Streams-0.2.2... Reading package info from ".installed-pkg-config" ... done. Warning: hiding the following packages to avoid conflict: ArrayRef-0.1.1 Streams-0.1.6 hiding old version of Stream library is correct, but why the hell it hides old ArrayRef library??? as the final result, both old and new ArrayRef libraries are hidden:
ghc-pkg list C:/Base/Compiler/ghc-6.4\package.conf: (ArrayRef-0.1), (ArrayRef-0.1.1), Cabal-1.1.4, GLUT-2.0, HGL-3.1, HUnit-1.1, OpenGL-2.0, QuickCheck-1.0, (Streams-0.1.6), Streams-0.2.2, Win32-1.0, base-1.0, (concurrent-1.0), (data-1.0), fgl-5.2, fps-0.7, haskell-src-1.0, haskell98-1.0, (hssource-1.0), (lang-1.0), mtl-1.0, (net-1.0), network-1.0, objectio-1.0, parsec-1.0, readline-1.0, rts-1.0, stm-1.0, template-haskell-1.0, (text-1.0), (util-1.0), (win32-1.0)
