I am getting this ALL of the time now. I haven't changed a thing; from what I remember this is libtool
getting confused about my compiler settings and so on, but I have no definitions set for CC, I didn't
change the compiler ever, I just don't understand why it spontaneously broke for everything. Previously
I was having trouble with the mod_python port which did this, but all my other modules worked fine.

Any clues on what I can rebuild/reconfigure in order to get this to work? It's important that we install
some new modules this week.
