Listen to Altoine, he knows what he's talking about. I fought with installation on RedHat 7.2 for about 3 hours before coming here. I had installed the JVM and the whole nine yards, but it still wouldn't install. I then followed his directions, and it installed flawlessly.

Step 1: Make sure you're trying to install from a normal user account, NOT root. If you're installing as root it will not work.

Step 2: Edit your .bash_profile, adding these lines (this is from my install):

export JAVA_HOME=/usr/java/jre1.3.1_03
export PATH=$JAVA_HOME/bin:$PATH

Step 3: Create a symbolic link to /usr/java/jre1.3.1_03/bin/.java_wrapper from /usr/bin/java. My system already had a file /usr/bin/java, so I deleted it and did the symbolic link:

ln -s /usr/java/jre1.3.1_03/bin/.java_wrapper /usr/bin/java

Step 4: Change to the owner of the install script (if necessary) and run it. It'll run flawlessly, and you'll then have Limewire on your system.
