[rkward-tracker] rkward does not start

[sdn]

Hello
When I try to start rkward i get the following error:

/usr/bin/rkward.bin: symbol lookup error: /usr/bin/rkward.bin: undefined 
symbol: R_LastvalueSymbol

I found only one similar problem in 
http://permalink.gmane.org/gmane.linux.debian.devel.bugs.general/302176

but no solution 

Any sugestion about that? 


System Debian / sid (sidux)
rkward 0.4.7a-1
R 2.6.0

Thank you
