Thanks for your reply but I’ve just installed libxml2-dev…
I don’t know what happens, One server have Ubuntu 9.04 and the other
Ubuntu 10.04 but int all the same error…

Might be a different lib you need. Try ‘apt-cache search libxml’ to
what else is available… might just be ‘libxml2’ you need, instead of
-dev. Or maybe ‘libxml-ruby(1.8|1.9.1)’.

Then again, this was exactly the problem I ran into when I was setting
up, and installing ‘libxml2-dev’ and ‘libxslt-dev’ resolved it. But if
you’re not getting an error on the latter, you would already have it.

Thanks for your reply but I’ve just installed libxml2-dev…

And also lib xslt dev?

What does
/var/lib/gems/1.8/gems/nokogiri-1.4.4/ext/nokogiri/gem_make.out say?

I’ve solve my problem doing that:
wget http://i.loveruby.net/archive/racc/racc-1.4.5-all.tar.gz
tar xzvf racc-1.4.5-all.tar.gz
cd racc-1.4.5-all
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install
gem install aaronp-frex -s http://gems.github.com
gem install nokogiri

I’ve find this post here:

Finally I’ve solved all my problem.
Thanks for your helps guys!!!
Byee!
