Ruby Installation

Hi
I have installed ruby from fedora repository (fedora12) with

yum install ruby ruby-devel ruby-docs ruby-irb ruby-libs ruby-mode
ruby-rdoc ruby-ri

And I got ruby --version
ruby 1.8.6 (2009-08-04 patchlevel 383) [i386-linux]

 This I did 2 months back . Now I am asked to repeat this process on

another machine. So my question is where can I find the same above
version with same patch . I looked in
www.ruby-lang.org It says about 1.8.7 and 1.9.1

 My second question is if I install 1.8.7 from source on the next

machine, will the application work? So what is the preferred way
Installing ruby from source or from a repository like fedora in my case?

Thanks
Tom

ftp.ruby-lang.org has all the previous version releases.

Probably. There are a number of changes in the ruby language for 1.8.7,
such that a program written for 1.8.7 may well not work in 1.8.6, but
one written for 1.8.6 probably works in 1.8.7.

If your distribution has a decent ruby repo, usually it’s a good idea to
use that. Your distribution should be keeping track of things like
security updates and you will automatically get a fixed version if you
need it. It also saves hassles in compilation (e.g. if you don’t have
the openssl-dev or zlib-dev packages installed when building yourself,
then important ruby extensions won’t be built)

HTH,

Brian.
