How do I install Oracle Client 32 bit 11.2.0.2 on RHEL Linux 64 bit?

Hi,

I need to install an Oracle Client 32 bit 11.2.0.2 on RHEL Linux 64 bit.

According to Bulletin 1075717.1, this should work, and it is supported:

The only release of 32-bit RDBMS Client software that will properly
install on an x86_64 Linux OS system is 11gR2 (aka 11.2.0.x)

Even so, I got this error in ./oraInventory/logs/installActions2012-02-14_xxxxx.log:
