All-righty, then.
I did not blow away this install. Most things worked the way it was expected to work. I was able to compile most programs, including custom kernels. But some things refused to go as planned - Bloodfrontier being one of these problems. Getting xconfig to work was another. I just refused to give up.
Today, I decided to revisit this vexing problem. Thanks to knudfl, I finally stumbled onto the problem. His above post about gcc headers made me search out and thoroughly through the system files. Those pesky includes were indeed missing. Since I am running -current, I had assumed that I upgraded gcc and indeed the 4.4.3 folder was in place. That said, none of the include files were in there anywhere. I am my own worst enemy(a).
Now one must wonder how I was ever able to compile anything? There is a simple answer to that as well. Alien's multilib 4.4.2 was still in place. I was running multilib at one point, then decided I didn't need that capability just for Google earth. I thought all of that was blown away at one point. I was wrong, and just plain brain dead in this case.
Bloodfrontier happily compiled just now. Xconfig is now working again, and I bet I solved a host of future problems as well.
I thank, and apologize to all that responded in this thread, and a thread I had for my problem with xconfig that was caused by my own stupidity. I will mark this as solved.
