Hi Jeong,

Like Mojca says, this is very strange. I've attached a trimmed-down
version of first-setup.sh with some debug print statements sprinkled
in; could you run that and post its output here? The output should be
something like this, possibly without the two 'branch' lines.

=== system branch is Linux: Linux
=== cpu branch is i*86: i686
=== system:   Linux
=== cpu:      i686
=== platform: linux

Cheers,
Sietse
