Viking 1.6.2 for Garmin etrex20

[CSNLinux]

A couple of days I'm looking for some software to run on LL for managing my Garmin etrex20.

Today I stumbled on Viking. Specs and screenshots look good.
After downloading the package and running the install commands as provided, my system tells me that

Code:

checking for intltool >= 0.35.0...  found
configure: error: Your intltool is too old.  You need intltool 0.35.0 or later.

But HOW to update this tool, it doesn't tell me

any suggestions ?
