You could try adding

LazyLoad: no

to your DESCRIPTION file although even if that works it may just get rid of the message and there may still be a real error in your package lurking. In the past I have found that often a lazyload error is not related to lazyloading at all and signifies some completely different error. Once I was able to get past it by using forward rather than backward slashes on a pathname in MS-Windows, for example. Another time I had to successively remove half my package until I pinpointed the real error. If you search the archives you can find comments similar to this by myself although I think I got the main points here.
