Oracle 9i, root.sh, installation problem

Hi!
I'm trying to install version 9.2.0.4 on Mandrake Linux 10 and in the last steps I must run the root.sh script in my Oracle Home folder (/oracle/ora92) as root. Here's what I get:
Running Oracle9 root.sh script...
./root.sh: line 1: /usr/bin/id: No such file or directory
./root.sh: line 77: [: !=: unary operator expected
\nThe following environment variables are set as:
ORACLE_OWNER= olivier
ORACLE_HOME= /oracle/ora92

Enter the full pathname of the local bin directory: [/usr/local/bin]: /usr/bin
Copying dbhome to /usr/bin ...
Copying oraenv to /usr/bin ...
Copying coraenv to /usr/bin ...

Adding entry to /etc/oratab file...
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
/bin/chmod: cannot access `/oracle/ora92/network/agent/html': No such file or directory

Do you see what to do? Thanks,
JB
