Business Objects XI 3.1 error while installling on Linux (Redhat Enterprise Linux)

When trying to install BusinessObjects XI 3.1 on Redhat Enterprise Linux 5 it gives that error:
Patch checking complete Can't load '/opt/boe/boxi3.1/perl/lib/site_perl/auto/XML/LibXML/Common/Common.so' for module XML::LibXML::Common: /opt/boe/boxi3.1/perl/extlibs/libz.so.1: cannot restore segment prot after reloc: Permission denied at /opt/boe/boxi3.1/perl/lib/5.8.8/i686-linux/DynaLoader.pm line 230. at /opt/boe/boxi3.1/perl/lib/site_perl/XML/LibXML.pm line 12 Compilation failed in require at /opt/boe/boxi3.1/perl/lib/site_perl/XML/LibXML.pm line 12.

The solution is to set the SELinux to enforce by issuing this command as root:
/usr/sbin/setenforce 0
(Note: 0 = Zero )
