cabal install yesod не удалось?

Зависимости пакетов Haskell по-прежнему являются проблемой, но я не знаю, как обойти эту проблему. Моя среда:

• Ubuntu 10.10, новая установка
• apt-get install ghc6 cabal-install
• cabal update && cabal install cabal-install

Затем:

• cabal install yesod

И я получаю это:

$ cabal install yesod
cabal: Error: some packages failed to install:
persistent-0.3.1.2 failed during the building phase. The exception was:
ExitFailure 1
yesod-0.6.6 depends on persistent-0.3.1.2 which failed to install.
$ cabal install persistent-0.3.1.2
Resolving dependencies...
cabal: cannot configure blaze-builder-0.2.0.2. It requires text ==0.10.*
For the dependency on text ==0.10.* there are these packages: text-0.10.0.0,
text-0.10.0.1 and text-0.10.0.2. However none of them are available.
text-0.10.0.0 was excluded because enumerator-0.4.3.1 requires text ==0.11.*
text-0.10.0.1 was excluded because enumerator-0.4.3.1 requires text ==0.11.*
text-0.10.0.2 was excluded because enumerator-0.4.3.1 requires text ==0.11.*

Как мне установить yesod?
