Hi, I installed the Haskell-Platform 2011.2.0.0 on my Mac with Mac OS X 10.6.6...and I am happy with it ;-) After some problems with directories and files under /private/var/folders, I get an error message whenever I try to use Cabal to install new packages. For instance: ................................................ cabal install sqlite Warning: The package list for 'hackage.haskell.org' is 28 days old. Run 'cabal update' to get the latest list of available packages. Resolving dependencies... Configuring sqlite-0.5.2... Warning: 'include-dirs: include' directory does not exist. Warning: 'hs-source-dirs: .' directory does not exist. cabal: Missing dependency on a foreign library: * Missing header file: sqlite3-local.h * Missing C library: sqlite3 This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is. cabal: Error: some packages failed to install: sqlite-0.5.2 failed while unpacking the package. The exception was: /var/folders/Ks/Ks-bTCXtGXaCQnMtMuXr4k+++TI/-Tmp-/sqlite-0.5.23531/sqlite-0.5.2: removeLink: permission denied (Operation not permitted) ................................................ "cabal update" works without an error message but generates the warning that the package list is old....? I assume that there is a permission problem with /private/var/folders but I dont know how to fix it. Regards Ulrich
