Error while installing DB2 10.1 fp1

Hello all,

I installed DB210.1 fp1 on RHEL 6.1 system.
While installing it gave this error:

#./installFixPack
Requirement not matched for DB2 database Server . Version: "10.1.0.1".
Summary of prerequisites that are not met on the current system:
DBT3514W The db2prereqcheck utility failed to find the following 32-bit library file: "/lib/libpam.so*".

But it continued installation & installation got completed successfully. Also there is no error mentioned in log file related to this.

So should I add this library to lib folder and uninstall and install fixpack again?or leave it like that. please help
