Hi.

Did you found a solution for this problem?
I got the same problem on debian and searched already a lot for 
solutions.

I found only that you may haven't installed zlib.  You can check this 
via:
---
# ruby -e "puts(require('zlib'))"
true
---
Unfortunately i get true back, but still got this error. Has anyone a 
idea?

Here are my details:
---

thx

Hi

yes, you have to install the ruby1.8-dev package from apt-get. this
problems are because of mixing apt-get with rails 2.0...
