"Can not crate release for linux distribution"

Hello,
I am trying to create a release for linux distribution.
I suppose that it is possible to do this through windows OS( I am using win 7).
Nevertheless, I get the following error:

BUILD FAILED
C:\Users\philo\workspace\RapidMiner_Unuk\build.xml:308: Problem: failed to create task or type antlib:org.freecompany.redline.ant:rpm
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet

This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
        -C:\Program Files\eclipse\plugins\org.apache.ant_1.8.3.v201301120609\lib
        -C:\Users\philo\.ant\lib
        -a directory added on the command line with the -lib argument
