[news.eclipse.technology.linuxtools] Can't install Linux Tools

[ermin.hasicevic@xxxxxxxxx (Ermin HasiÄ?eviÄ?)]

Hi, guys!

I try to install Linux tools from archive I downloaded from the internet. 
I instruct Eclipse update manager with the location of the archive and 
then start the installation process but I get error. I decided to install 
autotools for starters but for some reason update manager thinks that some 
other plugin that autotools relies on is missing. Error message is this:

Cannot complete the install because one or more required items could not 
be found.
 Software being installed: Autotools Feature (Incubation) 
1.0.3.200905251648 
(org.eclipse.linuxtools.cdt.autotools.feature.feature.group 
1.0.3.200905251648)
 Missing requirement: Autotools Feature (Incubation) 1.0.3.200905251648 
(org.eclipse.linuxtools.cdt.autotools.feature.feature.group 
1.0.3.200905251648) requires 'org.eclipse.cdt.make.core [5.0.0,6.0.0)' but 
it could not be found

I looked at the list of installed plugins and it says that it has:

org.eclipse.cdt.make.core (6.0.0.200905061052) "C/C++ Standard make Build 
Core" [Active]

Is there any way to manually override this?

I have Eclipse 3.5RC3 and CDT 6.0 (installed from latest CDT 6.0 master 
archive!) on my computer.
