Yes, and you will need a collection of other include files and libraries that 
are probably not installed on your system.

Building mod_jk on a RedHat system is slightly complicated by the fact that 
RedHat breaks up packages.

For example, if you install the apr and apr-util packages, you might expect to 
have all the tools required to build software with Apache's portable runtime 

You don't. You will need to install apr-devel and apr-util-devel in order to 
build other software using these libraries. The apr and apr-util packages 
contain only what is required to run software built with these packages.

Building mod_jk on RedHat (at least Fedora), requires a collection of 
development tools and packages. At the top of the requirements chain, these are:

1. httpd-devel
This package provides /usr/sbin/apxs among other things.

2. apr-devel
The include files for building software with the apache portable runtime 

3. apr-util-devel
The include files for the utilities library of the apache portable runtime 

4. Java JDK
Note, the JRE will NOT work. You should download and install this from Oracle, 
although there are ways to get this installed using the RedHat package manager. 
There are include files in $JAVA_HOME/include and $JAVA_HOME/include/linux that 
you will need.

If yum is set up properly (at least on Fedora), the dependencies for the first 
three packages will be pulled in when you request the following (as root):

yum install httpd-devel apr-devel apr-util-devel

In part, you should see the following get installed.

perl (if not installed already - can't imagine why it wouldn't be)
db4-devel (which requires db4 and db4-cxx)
expat-devel (which requires expat)
openldap-devel (which requires openldap,cyrus-sasl-devel)

cyrus-sasl-devel requires a set of packages as well.

Hopefully everything else should be in place on your system.

Again, in a sane world yum will pull in the required dependencies if you just 
do the following as root:

yum install httpd-devel apr-devel apr-util-devel

Yum will come back with a list of additional packages it needs to install in 
order to meet the requirements.

This is how it works on a Fedora system, which is basically the beta testing 
environment for RedHat EL releases.

For mod_ssl, you shouldn't have to build it. At least on a Fedora system, 
mod_ssl is provided by the mod_ssl package.

Installing that as root with:

yum install mod_ssl

will bring in the openssl package. You will need the openssl package and the 
openssl-devel package in order to build the Tomcat native libraries packaged in 

Hopefully between you and your system admin, you can decipher the above mail 

. . . . just my two cents.
