Error while running csscan v1.2 utility against 9.2.0.8

We are in the process of upgrading the database from 9i to 10gR2. I was running the csscan utility and got the following error:

csscan FULL=Y TOCHAR=al32utf8 LOG=dbcheck CAPTURE=N ARRAY=1000000 PROCESS=3
ld.so.1: csscan: fatal: /sfcnv/u60/oracle/product/9.2.0/lib/libclntsh.so.9.0: wrong ELF class: ELFCLASS32
Killed

I set the ld_library_path in my profile. lib32 library is missing.
From v$version, I found that database is at 9.2.0.8.

Please help!

I have been following the Metalink document 260192.1.
