Sorry my ignorance: but those files are small... and the files in http://thecust.net/nelisquare/hathor-sdk/ are big...¿?
And i don't understand which files go in each folder

0. Put scratchbox files to:

a./media/schturman/USB/NOKIA_N9/Scratchbox/harmattan/dists/parse/main/binary-amd64
Also download this file, extract and put it here.

b./media/schturman/USB/NOKIA_N9/Scratchbox/harmattan/dists/parse/main/binary-i386
Also download this file, extract and put it here.

c. /media/schturman/USB/NOKIA_N9/Scratchbox/rootstrap And inside here?

d. /media/schturman/USB/NOKIA_N9/Scratchbox/tarball And here?
