(so, typically this should rather go to R-devel than R-help;
 but never mind for this time.)

indeed, there aren't any in the CRAN packages.

If you don't get other feedback, do try to isolate the problem
into a very minimalistic example, and if the problem persists,
use R-devel 
and give the details {maybe a URL to download the package source} 
of your (minimalistic!) package setup.
Then, we can help you further.
