Error installing orocos-toolchain

Hello,

I tried installing orocos toolchain on debian squeeze by following the
steps listed at
http://www.orocos.org/wiki/orocos/toolchain/quick-start

ruby --version gives
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

when I do sh bootstrap.sh, I get

The current directory is not empty, continue bootstrapping anyway ?
[yes] yes
autodetecting the operating system
autoproj_bootstrap:360:in `operating_system': undefined method `map' for
nil:NilClass (NoMethodError)
from autoproj_bootstrap:267:in `supported_operating_system?'
from autoproj_bootstrap:854:in `define_osdeps_mode_option'
from autoproj_bootstrap:1603
.: 45: Can't open /home/frede/orocos-toolchain/env.sh

Any ideas what could be wrong?

Thanks in advance,
Sagar
