Hi,
Could anyone shed light on the meaning of this error message?
cabal: cannot configure xmonad-0.9.1 It requires base ==3.*
For the dependency on base ==3.* there are these packages:
base-3.0.3.1 and
base-3.0.3.2. However none of them are available.
base-3.0.3.1 was excluded because of the top level dependency base -
any
base-3.0.3.2 was excluded because of the top level dependency base -

Any hints?
Yes: use xmonad-0.9,2 instead! It supports base-4, which is probably
what you have (with GHC-7.0.*).
Indeed, I discovered that to be the solution in the meantime, as I
noticed that on my other system xmonad-0.9.2 was being installed by
cabal install. Doing a cabal update made everything go through (with
xmonad-0.9.2).
Which makes me wonder why the two systems had different ideas of what
the most recent xmonad version was, as I installed both of them
yesterday afternoon. I seem to be discovering a rule of thumb: do a
cabal update *every time* you want to cabal install.
Anyway, thanks for the hint.
