GRASS 6.4 RC5.9

After waiting so long for the ever-imminent release of GRASS 6.4RC6, and with other things piling up, I really needed to rebuild GRASS. This build is from the current SVN state of the 6.4 source, so I called it RC5.9 .

It now uses GDAL 1.7. To simplify installation I bundled the Tcl/Tk frameworks from ActiveState. And by popular demand (1 person many times?) I included the xganim tool (minimal testing, I hope it works OK).
