I am not sure why you start with this. If you do this for a clean start, see my http://www.vex.net/~trebla/haskell/sicp.xhtml#remove for why it is not a clean start. If you do this for some other purpose, nevermind.

... lots of output ...

I think that is the informative part.

This release has an important bug fix for the metadata download. When metadata was downloaded using libcurl it was not treated as binary data.  If you used one of our binary installers or if you built Leksah with the -flibcurl flag then it is likely you have bad metadata files.

I just tried (again) to install Leksah. I was wondering if you could point out where I go wrong. I'm on a fully up-to-date Gentoo Linux (kernel 3.4.3, 64 bit) box.

I ran the following commands (as described, more or less, on http://leksah.org/download.html):

hilco@centaur ~ ~$ rm -rf .cabal/

Any ideas?
