You can use ‘uname’ command.

uname -i will print your machine arch; i386 means 32bit, x86_64 for 64 bit arch.
uname -r prints your kernel version, if you have a 64bit kernel version running, you’ll notice it.

You need to update libpcap before install tcptrack

# yum install libpcap -y
# wget http://dag.wieers.com/rpm/packages/tcptrack/tcptrack-1.1.5-1.2.el5.rf.$(uname -m).rpm
# rpm -ivh tcptrack-1.1.5-1.2.el5.rf.$(uname -m).rpm
# tcptrack -i eth0
Done !!

If you got errors on dependencies probably you have a 32bit system so follow these steps:
# cd /tmp/
# wget http://dag.wieers.com/rpm/packages/tcptrack/tcptrack-1.1.5-1.2.el5.rf.i386.rpm
# rpm -hiv tcptrack-1.1.5-1.2.el5.rf.i386.rpm
Have a nice day!
