Hi, the GSoC implementation of v.mapcalc is still available: https://code.google.com/p/grass-gis-temporal-algebra/source/browse/#svn%2Ftrunk%2Fv.mapcalc
However, the approach in the GSoC v.mapcalc is very different from the v.mapcalc addon from 2002. The algebraic expressions are applied to whole vector maps, rather than single points, list of points, lines or polygons.
