+Because [IPset](http://ipset.netfilter.org/) is both a userspace utility
+and a set of kernel modules, it poses something of a challenge to
+compile. Here's how I did it:
+
+- Note that there are two extant versions of IPset that are designed
+  with different releases of the Linux kernel in mind:
+  - v4.5 is for Linux kernel \>= v2.6.16
+  - v6.10 is for Linux kernel \>= v2.6.**35**
+    - This version requires that a patch be applied to the kernel to
+      implement the IPset functionality before it'll work. Let's try
+      this last.
+    - The SlackBuild script checked into Git needs to be updated!
+- I used [this
+  procedure](http://porteus.org/info/docs/51-development/91-compilation-and-usage-of-custom-porteus-kernel.html)
+  to compile a Porteus kernel. Note that we're not actually replacing
+  000-kernel.xzm, but a fully configured and compiled kernel has to
+  exist on the system for IPset to compile. You just have to compile it,
+  not install it, not install new modules, and not rebuild
+  000-kernel.xzm.
+  - Don't forget to run **make modules**!
+- Once the kernel is compiled but not installed (on Windbringer running
+  VirtualBox this took about five hours) download and uncompress the
+  appropriate version of IPset.
+- I edited the Makefile to change the value of PREFIX to "/usr". I
+  recommend that you do this.
+- **su -**
+- **make KERNEL_DIR=/path/to/your/compiled/linux-2.6.38.8**
+- Pay close attention. If everything goes as planned it won't take long
+  to build.
+- If you do not start seeing output to the effect of **CC \[M\]
+  /home/guest/tmp/ipset-4.5/kernel/ip_set.o** you forgot to run **make
+  modules**. IPset will not work.
+- Now install the utility and kernel modules into a fakeroot so they can
+  be packaged:
+
+` `**`DESTDIR=/tmp/fakeroot make KERNEL_DIR=/path/to/your/compiled/linux-2.6.38.8 install`**
+
+- Now you have to manually package the kernel modules:
+
+` `**`mkdir -p /tmp/fakeroot/lib/modules/2.6.38.8-porteus/extra/`**
+` `**`cp /lib/modules/2.6.38.8-porteus/extra/ip* /tmp/fakeroot/lib/modules/2.6.38.8-porteus/extra`**
+
+- If no files exist in the fakeroot directory
+  */tmp/fakeroot/lib/modules/2.6.38.8-porteus/extra* then the kernel
+  modules will not be packaged and IPset will not work.
+- Strip the ipset binary to save space:
+
+` '`*`'strip /tmp/fakeroot/usr/sbin/ipset`*
+
+- If they do exist, build the .xzm package:
+
+` `**`dir2xzm /tmp/fakeroot /tmp/ipset-4.5.xzm`**
