Sorry guys , but I am trying to install the capybara gem on a Debian 5
server , ( Ruby 1.9.2 , Rails 3.0.5) and I am getting in trouble with
some dependencies ... I would like to chek if it's not related to
ffi ..

I am getting this error ONLY when installing with Ruby 1.9.2 ( Rails
3.0.5) on a remote Debian5  server...
I already installed it on this remote server w Ruby 1.8.7 (Rails
2.3.11) and previously on a Centos5 remote server and on my local Mac
OSX)...

so my questions are :
1- is it linked to the server libraries ?
2- if yes, are the lib different for ruby 1.8.7 and 1.9.2 and
different for Debian 5 , Debian 6 ?
3- Is there any incompatibility to have these libraries on Debian5 and
ruby 1.9.2 ?

thanks for your feedback, continuing googling around ....
