A Blessing on Making the Lulav

Yerushalmi 3:4 records:

One that makes a Lulav for himself says:

Blessed... that sanctified us with His commandments and commanded us to make a Lulav.

For another, one says: to make a Lulav in his name.

When he takes the Lulav, he says:

Blessed... that sanctified us with His commandments and commanded us to about the taking of the Lulav.

Prays with it, he says Shecheyanu, and makes a blessing every time he takes it.

There is then a machloket as to the blessing made on the last 6 days of Sukkot:

1. The same ending
2. ending with "that commanded us on the commandments of the elders" (since it is all d'rabbanan at that point).
3. No blessing at all for the other days, like D'mai, another mitzvah d'rabbanan, has no blessing.
