[tycho-user] [issues building using tycho .15 and target to eclipse 3.6]

Hello All,
I have been trying to build RSE using tycho for some weeks now,

and there is one issue that I can not get rid of, unless I change the
eclipse site url to use indigo or juno (I don't even have to change the
tolerance for the eclipse site, I left it as [3.6,3.7)

Im trying to build using helios, but seems like the repositories are
missing something, or can not be understood by tycho

I use eclipse site
http://download.eclipse.org/releases/helios
cdt site
http://download.eclipse.org/tools/cdt/updates/helios/

Tycho version is : .15
and the RSE version Im trying to build is 3.2.x

When the build gets to resolving dependencies (hudson log is here
https://hudson.eclipse.org/sandbox/job/target-management/11/console)
it fails with the following error
