Please check the file /home/ttamba/grassdata/nc_spm_08/landsat/.gislock for ownership and date. Since it is in your home and not a network directory, this happens if you try to open more than one GRASS GIS sessions in the same *mapset*. You can work in the same location with more sessions (also run by other users) but not in the same mapset. See also here: http://grasswiki.osgeo.org/wiki/Location_and_Mapsets If it is a leftover outdated file and no GRASS session is running therein, then you can simply remove it. Note that recent GRASS versions open a related dialog.
