How to install Ruby On Rails on Linux (SuSE) with console support

I am installing Ruby On Rails on SLES 10, http://www.novell.com/documentation/sles10/esd/di_sles10_vmware.html.

All was fine until I tried to start the console. From Google I think I learned that readline and readline-devel need to be installed to be able to run the console.

I now have readline and readline-devel installed. I recompiled Ruby and RubyGems. The console still fails with the same message that readline is missing.

To recompile:
user@SRC-DEV-VAS123:~/soft> export RUN=${HOME}/packages
user@SRC-DEV-VAS123:~/soft> tar zxvf ruby-1.8.6.tar.gz
user@SRC-DEV-VAS123:~/soft> cd ruby-1.8.6
user@SRC-DEV-VAS123:~/soft/ruby-1.8.6> ./configure --prefix=/usr
user@SRC-DEV-VAS123:~/soft/ruby-1.8.6> make
user@SRC-DEV-VAS123:~/soft/ruby-1.8.6> sudo make install
user@SRC-DEV-VAS123:~/soft/ruby-1.8.6> cd ..
user@SRC-DEV-VAS123:~/soft> tar zxvf rubygems-0.9.4.tgz
user@SRC-DEV-VAS123:~/soft> cd rubygems-0.9.9.4
user@SRC-DEV-VAS123:~/soft/rubygems-0.9.4> sudo ruby ./setup.rb
