Down load SlackBuild here

I made a SlackBuild so it would be easy to build the package. I made the SlackBuild in the fashion of SlackBuild.org and submitted it to them. You can find the source file here

I think its very important to support the GNU version vs supporting the official version. Thanks for every ones help and I hope others find it useful.

I don't mean to rain on your parade, but I don't think it will be accepted to slackbuilds.org just because of the nature of the program. slackbuilds.org doesn't like to interfere with official packages, and IceCat is basically just a Firefox clone without some proprietary eye-candy. I personally think the whole Ice* mods are a collosal time-waster, but if you want to 'support the cause' (which doesn't make sense to me since Firefox essentially is open-source anyway), hosting it on your own website is a good idea (and since you've posted here people can find it now).

To sum up: it probably won't be accepted to slackbuilds.org (though I am not affiliated with them in any way, so I could be wrong) -- but hosting it on your own site should be enough, since everyone can access it.
