Now I'm able to build froyo image, but I have an error flashing it.
The error is :
fastboot update Dream.zip -w
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
--------------------------------------------
Bootloader Version...: 0.95.3000
Baseband Version.....: 2.22.19.26I
Serial Number........: HT91RL(XXXXXX)

Device version-baseband is '2.22.19.26I'.
Update requires '2.22.26.07'.
finished. total time: 0.070s
The solution is:
Open the board-info.txt and replace
require version-baseband=2.22.26.07
with this
require version-baseband=2.22.19.26I>
Happy flashing
