I'd like to make some development for N900.

I tried to install scratchbox the graphical way :
sudo ./maemo-sdk-install-wizard_5.0.py

It works until 30%, then I get an error :

Setting up 'FREMANTLE_ARMEL' target.
Inconsistency detected by ld.so: rtld.c: 1192: dl_main: Assertion `(void *) ph->p_vaddr == _rtld_local._dl_sysinfo_dso' failed!

You dont have active target in scratchbox chroot.
Please create one by running "sb-menu" before continuing

So, I try to run sb-menu
Traceback (most recent call last):
File "/usr/bin/sb-menu", line 10, in <module>
os.execv(chroot,[chroot,p.basename(sys.argv[0])]+sys.argv[1:])
OSError: [Errno 13] Permission denied

sudo sb-menu
[sudo] password for delafond:
ERROR: Not allowed to run this as root!

All information will be received with pleaure ;-)
