Problems updating cabal-install on Mac OS

Hi Cafe, I just installed the brand new Haskell Platform 2012.4.0.0 for Mac OS X, 32 bit, after removing everything left over from the old one (I hope). Next I started cabal which said to me:
Downloading the latest package list from hackage.haskell.org Note: there is a new version of cabal-install available. To upgrade, run: cabal install cabal-install
So next I did cabal install cabal-install which started working
Resolving dependencies... Downloading Cabal-1.16.0.2...
and finished with
Installing executable(s) in /Users/bo/Library/Haskell/ghc-7.4.2/lib/cabal-install-1.16.0.1/bin Updating documentation index /Users/bo/Library/Haskell/doc/index.html
When I then tried cabal update it still said
Downloading the latest package list from hackage.haskell.org Note: there is a new version of cabal-install available. To upgrade, run: cabal install cabal-install
I thought I just had done that. What could have gone wrong?
Haralds-iMac:~ bo$ which cabal /Users/bo/Library/Haskell/bin/cabal Haralds-iMac:~ bo$ ls -l `which cabal` lrwxr-xr-x 1 bo staff 49 6 Nov 18:15 /Users/bo/Library/Haskell/bin/cabal -> ../ghc-7.4.2/lib/cabal-install-1.16.0.1/bin/cabal
Now that I am writing this up I am noticing that the last thing that
seems to be installed has version number 1.16.0.1, while it started out
with 1.16.0.2.
So on a second thought I am attaching the full log of the install.
Am I doing anything wrong?

Did you do "hash -r" so your shell will forget that it had already found cabal in /usr/bin? (This is not a Mac OS X thing, it's a bash and zsh thing. csh/tcsh does it too but you clear its path hash table with "rehash".) -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix/linux, openafs, kerberos, infrastructure http://sinenomine.net

Oops, you are right! Now it seems to work, stupid me!
I thought that by issuing these two commands
Haralds-iMac:~ bo$ which cabal
/Users/bo/Library/Haskell/bin/cabal
Haralds-iMac:~ bo$ ls -l `which cabal`
lrwxr-xr-x 1 bo staff 49 6 Nov 18:15
/Users/bo/Library/Haskell/bin/cabal ->
../ghc-7.4.2/lib/cabal-install-1.16.0.1/bin/cabal
I had made sure I was using the new version. But apparently not!
Thanks a lot!
(I still find it mildly confusing that there are two different version
numbers involved:
Haralds-iMac:~ bo$ cabal --version
cabal-install version 1.16.0.1
using version 1.16.0.2 of the Cabal library
but that seems to be ok?)

3@haral:117 B$ type which which is /usr/bin/which It's not a bash builtin, so it doesn't show the current shell's idea of the world. "type" will show you that. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix/linux, openafs, kerberos, infrastructure http://sinenomine.net
