I don't know what the problem is but you could see if adding

LazyLoad: no

to the DESCRIPTION file causes it to go away.  Even if it does it
would probably be best to track down what the cause is and in the past 
when I have had problems running R CMD on a package of mine I 
repeatedly removed half my package and reran R CMD until I found the 
offending portion.
