Before installing MPP GUI / Qreview we are going to install the following requirements:
- libexpat
- libgd
- MySQL client (libmyclient(_r).so)
- Perl modules
    1.  DBI
    2.  DBD::MySQL
    3.  XML::Parser
    4.  XML::Generator
    5.  MIME::Tools
    6.  GD::Graph
    7.  URI
    8.  Net::SSLeay
    9.  Crypt::OpenSSL::DSA

Certain updates are not available through RedHat Network Update (up2date or yum). 
For this reason I have used DAG repository (http://dag.wieers.com/rpm/FAQ.php#B)to install: 
perl-MIME-tools and perl-GD-Graph (along with their dependencies)
rpm -Uhv http://apt.sw.be/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
yum update 
or
up2date -u

yum install gd gd-progs perl-DBI perl-URI mysql mysql-devel mysql-server perl-DBD-MySQL perl-XML-Parser \ 
 perl-Net-SSLeay perl-MailTools perl-MIME-tools perl-GD perl-GD-Text-Util perl-GD-Graph perl-Crypt-OpenSSL-DSA \
 perl-OODoc antiword poppler-utils
or 
up2date -i gd gd-progs perl-DBI perl-URI mysql mysql-devel mysql-server perl-DBD-MySQL perl-XML-Parser \ 
 perl-Net-SSLeay perl-MailTools perl-MIME-tools perl-GD perl-GD-Text-Util perl-GD-Graph perl-Crypt-OpenSSL-DSA \
 perl-OODoc antiword poppler-utils

rm -rf mppmanager mppmanager.tar.gz
wget -c ftp://ftp.messagepartners.com/pub/mppmanager/beta/mppmanager.tar.gz
tar xzvf mppmanager.tar.gz
cd mppmanager
./setup.pl
