+Followed the instructions over here: http://git-annex.branchable.com/forum/git-annex_on_OSX/
+
+and had to install the following extra packages to be able to get make to start:
+
+[realizes pcre-light is needed but pcre not installed on my mac]
+sudo port install pcre
+sudo cabal install pcre-light
+
+But then I got the following error:
+
+ghc -O2 -Wall --make git-annex
+[ 7 of 52] Compiling BackendTypes     ( BackendTypes.hs, BackendTypes.o 
+
+BackendTypes.hs:71:17:
+    No instance for (Arbitrary Char)
+      arising from a use of `arbitrary' at BackendTypes.hs:71:17-25
+    Possible fix: add an instance declaration for (Arbitrary Char)
+    In a stmt of a 'do' expression: backendname <- arbitrary
+    In the expression:
+        do backendname <- arbitrary
+           keyname <- arbitrary
+             return $ Key (backendname, keyname)
+    In the definition of `arbitrary':
+        arbitrary = do backendname <- arbitrary
+                       keyname <- arbitrary
+                         return $ Key (backendname, keyname)
+make: *** [git-annex] Error 1

+My knowledge of Haskell (had to lookup the spelling...) is more than rudimentary so any help would be appreciated.
