When i try to install rails in Ubuntu 12.10 = i get this error:

[CODE] =A0 =A0$ gem install rails
=A0 =A0 ERROR: Loading command: install (LoadError)
=A0 =A0 cannot load such file -- zlib
=A0 =A0 ERROR: While executing gem ... (NameError)
=A0 =A0 uninitialized constant Gem::Commands::InstallCommand[/CODE]

So i completely removed rvm:

[CODE]rvm implode
=A0 =A0 sudo rm -rf ~/.rvm[/CODE]removed the script calls in my .bashrc and=
.bash_profile

and checked if they're really removed:

[CODE]env | grep rvm #no output, so rvm is removed
=A0 =A0 ruby -v #The program 'ruby' can be found in the following p= ackages:
blabla[/CODE]

I already have these via sudo apt-get install:

[CODE]curl zlib1g-dev zlib1g libssl-dev build-essential openssl
libreadline6 libreadline6-dev curl git-core libyaml-dev libsqlite3-dev
sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake
libtool bison subversion pkg-config[/CODE]

Then proceed to install from scratch

[CODE]curl -L https://get.= rvm.io | bash -s stable --ruby
--auto-dotfiles[/CODE]

then run that line and restarted terminal regard to this message:

[CODE]* To start using RVM you need to run `source
/home/adige/.rvm/scripts/rvm`
=A0 =A0 =A0 =A0 in all your open shell windows, in rare cases you need to r= eopen
all shell windows.[/CODE]

Then

[CODE]rvm pkg install readline[/CODE]

but completed with error:

[CODE]...
=A0 =A0 Error running 'autoreconf -is --force', please read
/home/adige/.rvm/log/readline/autoreconf.log
=A0 =A0 ...
=A0 =A0 Please note that it's required to reinstall all rubies:

=A0 =A0 =A0 =A0 rvm reinstall all --force[/CODE]

I think it's installed anyway, right? Before reinstall all rubies, i installed zlib of course:

[CODE]# w/out verify, it gives checksum error
=A0 =A0 rvm pkg install zlib --verify-downloads 1[/CODE]

Then run

[CODE]rvm reinstall all --force[/CODE]

and completed with error again:

[CODE]...
=A0 =A0 Install of ruby-1.9.3-p374 - #complete

=A0 =A0 Error running '' under ,

pristine.[/CODE]

gemset.pristine.log: http://pastebin.com/ZrmWStNB

Then reinstall ruby with zlib support:

[CODE]rvm reinstall 1.9.3-p374 --with-zlib-dir=3D$rvm_path/usr[/CODE]

which returned same error and same log(http://pastebin.com/ZrmWStNB) but
completed anyway.

Finally i tried to install rails gem again but

[CODE]cannot load such file -- zlib ![/CODE]

Here is the rvm info: http://pastebin.com/08fp9PVW

What am i doing wrong?
