LinuxQuestions.org - Splunk Error on FC3 Box

Okay I'm trying to install Splunk on all of our servers. The newer servers don't seem to take issue with it, but we have five older servers that are giving me this message.

Code:

Verifying configuration.  This may take a while...

python: /lib/i686/libc.so.6: version `GLIBC_2.3' not found (required by /splunk/lib/libpython2.4.so.1.0)

python: /lib/i686/libc.so.6: version `GLIBC_2.3' not found (required by /splunk/lib/libstdc++.so.6)

Finished verifying configuration.

Checking index directory...

python: /lib/i686/libc.so.6: version `GLIBC_2.3' not found (required by /splunk/lib/libpython2.4.so.1.0)

python: /lib/i686/libc.so.6: version `GLIBC_2.3' not found (required by /splunk/lib/libstdc++.so.6)

Your datastore's directory structure does not seem to be correct. Do you want Splunk to correct it? [y/N]:

I'm pretty sure it's just because of outdated libraries but I am hesitant to update them because of bad prior experiences. If I just yum update the glib - will that fix the issue or will it cause more problems? Or both?

The servers it does not run on are running fc3. However, some of the newer boxes are also running fc3 but most are running centos 4.
