Your ruby version is too old; see README
Thanks for the tip, but it doesn't seem like the ruby version is too old, it is 1.8.4
which is the requirement in the README for s3sync.rb
$ cat README.txt
--- SNIP ---
Prerequisites:
--------------
You need a functioning Ruby (>=1.8.4) installation, as well as the OpenSSL ruby
library (which may or may not come with your ruby).
--- END SNIP ---
$ ruby --version
ruby 1.8.4 (2005-12-24) [i486-linux]
It seems more like i could need som help on how to get openssl support compiled into a fresh ruby installation
on a Debian system as the debian package openssl-ruby doesn't help (maybe too old, who knows)
Best,
Redox
