Subject: Array to Hash in 1.8.6 vs 1.8.7

I'm damn toast!

My dev machine runs a manually compiled 1.8.7 version of Ruby. My server
runs a Debian Etch with Ruby 1.8.6 version.

From a string:

1:2_5:6

I want to convert it to a hash: {"1" => "2", "5" => "6"}

On my dev machine the following works:
Hash[(session.split("_").map { |couples| couples.split(":") }).flatten]

On my server it pukes on me with the following error:
odd number of arguments for Hash

How can I fix it with Ruby 1.8.6 and 1.8.7 compatibility? I don't want
to play with the Ruby version of Debian etch as it's the latest
available package.


Many thanks in advance.
