Gems not installing because of "invalid stored block lengths"

I've been struggling the whole day today with this. I got ruby on my machine ('buntu 10.04), got rubyGems, but I cant install a single gem! I am trying to get rails up and running. Directly downloading from the website does not work either. What's going on?

Please provide exact output that you're getting, including the output of gem env and the output of the gem installation process with --debug -V options.

That way we are going to be able to help you better.

I removed all traces of ruby and rubygems, and started over. Here follows the complete output:

I hope this tells you what the problem is. I already tried downloading from the website, but that did not work either. Another user had a similar problem.

```

Setting up rubygems (1.3.5-1ubuntu2) …
```
Followed by:
```
  - RUBYGEMS VERSION: 1.7.1
```
So you're not using RubyGems 1.3.5.

If you're getting zlib data errors you have a problem with your network or a broken install of ruby.

Hello

Sorry for being so quiet lately. I've been crazy busy.

No I have not managed to get it running using the method above.
At the end I had to compile RVM from scratch, and use that to compile and install ruby and gems.

Somewhere along the package stream there was a broken package, and it messed up everything downstream. The fact that I compiled most of it on my machine at the end, fixed it.

Thanks! :-)
