You only get a message like this if rast.put() is being run 
with interp=TRUE. However this is confusing, because sites.get() 
must have worked correctly! Please note that there is a mailing list for 
interface questions at http://grass.itc.it/statsgrass/index.html. Can you 
provide more details, interface version number (help(package=GRASS)), on 
that list or directly?
