yes (from R to grass is ok - I followed your example with meuse data
just fine)

no

no, readOGR() works fine (tried with shapefiles)

ok many thanks - I think that I understand the problem now (but I will
not do anything about it for the moment, as I want to be able to work
with grass6.4.3 as well).

I can import my spatial data to R one way or another, I was just hoping
that there would be a way for the grass package to recognise the right
versions without making redundant one version in favor of another.
