Please make that: http://grass.itc.it/newsletter/index.php - the article 
is the the GRASS Newsletter volume 3, June 2005, pp. 11-16, and an erratum 
is there too for difficulties installing on a server rather than a 
workstation. 

rast.get() is replaced in the new framework by readFLOATsp() and 
readCELLsp(), so you will have to change your code; in addition, the 
objects returned are different too.
