Michael,
I could not open the file in GRASS either. I have attached the errors I got.
They look like the same that you were describing (I tried both with and without
the -o flag). I did however remember the work around I used, which was to:
1. import the .nc files into MATLAB
2. Export as GeoTIffs
3. Read the GeoTiffs into GRASS
This made sense for me partly because I needed to aggregate daily values to
monthly means which I did in step 1, but then never thought much more about why
I couldn't import directly into GRASS . Your problem motivated me to look into
why I needed this workaround in the first place (which is not much of a
workaround unless you have access to MATLAB)… which appears to be that my gdal
does not have GMT/netcdf support either (as Markus pointed out yesterday). I am
also using WIlliams binaries and frameworks.
I agree that more detail in the wiki would be helpful, but I think the first
step is to compile to update gdal with GMT/NetCDF support. Perhaps William
would be interested?

GRASS ERRORS:

input=~/Desktop/ppt_SRESA2_mid_annual_down_anomaly.nc
output=ppt_SRESA2_mid_annual_down_anomaly
ERROR: Projection of dataset does not appear to match current location.

Import dataset PROJ_INFO is:

You can use the -o flag to r.in.gdal to override this check and use
the location definition for the dataset.
Consider generating a new location from the input dataset using the
'location' parameter.
