[Haskell-cafe] Really impossible to reinstall `base' using cabal?

[Captain Freako]

In response to this:

dbanas at dbanas-eeepc:~$ cabal install arrows
Resolving dependencies...
Configuring lazysmallcheck-0.6...
Preprocessing library lazysmallcheck-0.6...
Building lazysmallcheck-0.6...
[1 of 1] Compiling Test.LazySmallCheck ( Test/LazySmallCheck.hs,
dist/build/Test/LazySmallCheck.o )

Implicit import declaration:
    Could not find module `Prelude':
      Perhaps you haven't installed the "dyn" libraries for package `base'?
      Use -v to see a list of the files searched for.
cabal: Error: some packages failed to install:
Stream-0.4.6 depends on lazysmallcheck-0.6 which failed to install.
arrows-0.4.4.0 depends on lazysmallcheck-0.6 which failed to install.
lazysmallcheck-0.6 failed during the building phase. The exception was:
ExitFailure 1

I did this:

dbanas at dbanas-eeepc:~$ cabal install base

and got this:

Resolving dependencies...
cabal: internal error: impossible

Is it really impossible to use cabal to reinstall `base'?

Thanks,
