As it turns out if you want to have IPv6 support in the popular web proxy squid then you need to be using the cutting edge code available via CVS. This of course means that you are trying to get working code that others are still working on. Not the best situation but I'm hoping that I can get around anything that is still broken.
So far I have found a dependance on uudecode (for the icons). Of course uudecode is no longer distributed with Fedora. You only get a program called uudeview which I can only assume has the same calling semantics as uudecode. Here's hoping because currently the icons extraction doesn't work and therefore the make install doesn't working. So I am now manually trawling through the code doing manual makes where ever I think they are needed to get around this.
Getting closer.
