Oops, you are right! Now it seems to work, stupid me!

I thought that by issuing these two commands

Haralds-iMac:~ bo$ which 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 ->

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
using version of the Cabal library

but that seems to be ok?)
