[Installation] base-3.0.3.2 requires syb ==0.1.0.2

Hi, another installation issue on Ubuntu Lucid:

I started with a clean ~/.cabal directory and did the following:

andreas@antares:~$ sudo aptitude install cabal-install
andreas@antares:~$ cabal update
andreas@antares:~$ cabal install git-annex -v --bindir=$HOME/

However, I got some dpendancy error:

cabal: dependencies conflict: base-3.0.3.2 requires syb ==0.1.0.2 however
syb-0.1.0.2 was excluded because json-0.5 requires syb >=0.3.3

Any ideas?

Thanks for your help!
