My impression is mostly second-hand - it's Mike who does most of the running away, since he installs the tools we use.
What I hear is that DJB software is installed in non-standard places, that he's constantly changing where it goes and how it gets installed, and that he is incredibly arrogant and nasty to anyone who even dares ask why. He also doesn't trust standard libraries so he writes all the code he needs himself instead of linking out. Just a small ego problem, I guess. :)
My impression may be inaccurate - but I've read other references here in these forums to him being quite the nutcase. IMHO we have enough necessary complication in our lives without adding the unnecessary.
