The new release of spgrass6, the package interfacing R and GRASS 6 and 7, 
includes changes in the way commands are handled. Users should continue to 
use their scripts unchanged, but internally on "unix" platforms (all but 
Windows), GRASS error messages are now trapped in R and will issue stop() 
or warning() calls, rather than simply being printed to console and not 
being "seen" by the R process. This involved substituting system2() for 
system() in the package code in a number of places. Please report directly 
to the maintainer if problems arise.

Thanks to Rainer Krug for ideas and help testing.
