this version is severely outdated :x. Please use a recent version 
(read: the current snapshot or svn head) unless you have a very good 
reason not to. Especially since it already contains features such as 
minimal uclibc for core programs, which you obviously want.
Using recent versions will also help us help you, as a lot has changed 
in over 3 years.

Best regards
