error on building tool_chain_rump

[Jan-Ralph Sroka]

Hello everyone,

following the release-notes 14.05 I try to build the tool_chain_rump.

I am running Ubuntu 16.04 LTS.

Maybe someone can point out my mistake or refer me to a file with  
instructions since i was not able to
find one myself.


I get the following Output:
