can I suggest you to use the python interface to r.mapcalc [0]

http://grass.osgeo.org/grass71/manuals/libpython/script.html#script.raster.mapcalc

parse_command it should be used only to read the output of module
using the '-g' flag for shell style output, not to run modules that
are doing analysis
