arora 0.5 and qt 4.5 in debian experimental

i'm typing this from an arora 0.5 with qt 4.5 and debian experimental
http://packages.debian.org/experimental/arora
how did i installed it ?
i installed from stable then dist-upgraded to testing and then
unstable
here is how my sources.list looks like
cat /etc/apt/sources.list
deb http://ftp.us.debian.org/debian/ unstable main non-free contrib
deb-src http://ftp.us.debian.org/debian/ unstable main non-free
contrib
Add:
deb http://ftp.us.debian.org/debian/ experimental main non-free
contrib
deb-src http://ftp.us.debian.org/debian/ experimental main non-free
contrib
Then:
# aptitude update
# aptitude install -t experimental arora
my next thing is to build the 0.6 on it :)
