IPFire is based on Linux From Scratch: "Linux From Scratch is a project that provides you with step-by-step instructions for building your own custom Linux system, entirely from source code". So it is very likely that you also need to compile bitcoind by yourself.
I surely will have to compile from the sources. The question is, will all dependencies be able to compile there as well? Nothing (except git) is in those repos..
Well, I'll either find out, or will run bitcoind elsewhere. But 24/7 fullnode is a must! :-)
