R help - Jan 2013 - R-Forge package check error. Package dependencies on linux platform

Dear All,
I've got an error in R-Forge package check. when it checks with windows and
mac platform it doesn't give an error except one note which is regarding to
maintainer. However, it doesn't check correctly regarding to Linux platform
and gives me the following error. Due to this error I couldn't submit my
package to cran. Please help me how to solve the problem.
