Problems installing 7.6.2 on MACOS

[Dominic Steinitz]

Hi,

I followed the instructions pointed to from here: http://www.haskell.org/ghc/download_ghc_7_6_2#macosx_x86_64

> bash-3.2$ ./configure --prefix=/Library/Haskell


> bash-3.2$ sudo make install


But sadly I get:

> bash-3.2$ ghc-pkg list
> ghc-pkg: missing --global-package-db option, location of global package database unknown


and

> bash-3.2$ ghc --make nnClassifier.lhs -O2
> ghc: missing -B<dir> option


Any advice on how to get 7.6.2 working would be much appreciated.

Dominic.

Here's some more information:

> bash-3.2$ which ghc-pkg
> /Library/Haskell/lib/ghc-7.6.2/ghc-pkg
> bash-3.2$ which ghc
> /Library/Haskell/lib/ghc-7.6.2/ghc

7.4.1 still works fine:

> bash-3.2$ ghc-pkg-7.4.1 list
> /Library/Frameworks/GHC.framework/Versions/7.4.1-x86_64/usr/lib/ghc-7.4.1/package.conf.d:
