Most likely you will need a c compiler and kernel source to get the tools installed. If IPCOP has those available then things should work. Otherwise you will need an IPCOP dev environment to create the packages.

Check this post regards the IPCop 1.4.11 Virtual Appliance (http://www.vmware.com/appliances/directory/391) which indicate the steps they tool to integrate the tools
From the notes of the post.
"The appliance was built using the CVS version of IPCop 1.4.x, which at the
time of submission, is 1.4.11. In addition to the default installation that
results from building the system, this appliance also includes the complete
Linux From Scratch (LFS) platform that IPCop was built from. The LFS
distribution was included so that the appliance can run VMware Tools and
the user can easily upgrade to a new version, as well as install the
VMware Tools that may be specific to the VMware platform they intend to
run this appliance on."
