Mailgraph install on CentOS 5

Been with a lot of work this week, most of the time busy and pressured with our mail server migration, so, I took a bit of a time off from the box yesterday.

Mailgraph is a very cool utility to graph (duh !) the behavior of your mail server's ability to send, reject & bounce emails.

Installing it is pretty simple, it is a Perl script after all, simply untar the package and copy the Perl script and the init script, edit the some values of the init script, and you are done.
The thing is, the Perl script has some dependencies, most of them dealing with the RRD package.

Personally, I prefer not to touch the repos that the default yum install use on the servers, so here is a round down of the necessary steps to make the installation work, using all the packages from DAG.

[web10 rpms]# sudo rpm --test -ivh rrdtool-1.2.23-1.el5.rf.i386.rpm
warning: rrdtool-1.2.23-1.el5.rf.i386.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
error: Failed dependencies:
        libart_lgpl_2.so.2 is needed by rrdtool-1.2.23-1.el5.rf.i386
        perl(RRDp) is needed by rrdtool-1.2.23-1.el5.rf.i386
        perl(RRDs) is needed by rrdtool-1.2.23-1.el5.rf.i386

According to Egopoly, you need this packages first hand:

[web10 rpms]# sudo yum install libpng-devel \
freetype freetype-devel libart_lgpl-devel

After that, you'll still have problems (Egopoly seems to be compiling from source):

[web10 rpms]# sudo rpm --test -ivh rrdtool-1.2.23-1.el5.rf.i386.rpm
warning: rrdtool-1.2.23-1.el5.rf.i386.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
error: Failed dependencies:
        perl(RRDp) is needed by rrdtool-1.2.23-1.el5.rf.i386
        perl(RRDs) is needed by rrdtool-1.2.23-1.el5.rf.i386

So, get Perl-RRDTool first:

[web10 rpms]# sudo rpm --test -ivh perl-rrdtool-1.2.23-1.el5.rf.i386.rpm
warning: perl-rrdtool-1.2.23-1.el5.rf.i386.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
error: Failed dependencies:
        librrd.so.2 is needed by perl-rrdtool-1.2.23-1.el5.rf.i386
        rrdtool = 1.2.23 is needed by perl-rrdtool-1.2.23-1.el5.rf.i386

There is still a dependency problem, so, you'll have to install both packages at the same time:

rpm --test -ivh perl-rrdtool-1.2.23-1.el5.rf.i386.rpm \
rrdtool-1.2.23-1.el5.rf.i386.rpm rrdtool-devel-1.2.23-1.el5.rf.i386.rpm

You'll still need to install the last rpm package to get Mailgraph up & running:

[web10 rpms]# sudo rpm -ivh perl-File-Tail-0.99.3-1.2.el5.rf.noarch.rpm
warning: perl-File-Tail-0.99.3-1.2.el5.rf.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
