FileNet 5 ConfigMgr does not start on RedHat 6

After installing FN Content Engine (5.2 in my case) you want to run configmgr.
But it does not run without any errors.
Go to /root/configmgr_workspace/.metadata/.log and look at:

java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
 /ibm/fnce52/ContentEngine/tools/configure/configuration/org.eclipse.osgi/bundles/93/1/.cp/libswt-pi-gtk-3740.so (libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory)
 swt-pi-gtk (Not found in java.library.path)
 /root/.swt/lib/linux/x86/libswt-pi-gtk-3740.so (libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory)
 /root/.swt/lib/linux/x86/libswt-pi-gtk.so (/root/.swt/lib/linux/x86/liblibswt-pi-gtk.so.so: cannot open shared object file: No such file or directory)

You need to install x32 gtk library.

>yum install gtk2
>yum install gtk2.i686

BTW, if you cannot run CE installator on RHEL, check necessary libraries and use the command:

./5.2.0.3-P8CPE-LINUX-FP003.BIN LAX_VM /usr/bin/java
