[R] error preparing a package for lazy loading with R CMD

Tue Jan 25 09:05:02 CET 2005

A wild guess: Do you have one file one function? Could it be that the last
line in one of the files does not end with a newline and this is not taken
care of by the build with lazy loading? Try to add a newline at the end of
each of your files.
