Thanks. The most likely cause is that the system is not being identified 
as a "windows" system. Could you copy the output from your running R 
within GRASS of .sessionInfo() and of Sys.getenv() into an RData file 
(save()) and pass it to me off-list? The specific test expects 
.Platform$OS.type == "windows", and if it isn't, there may be issues. The 
other possibility is that Sys.getenv("OSTYPE") isn't known.
