Kris Kennaway first pointed this out to me. As I understand it, this is
because cfengine isn't really supposed to be linked against libc_r. cfd is
a threaded program and as such needs to be linked againt libc_r. Meanwhile
cfengine isn't threaded and is supposed to be linked against libc. But in
the way the compilation is done, it's one or the other. Anyway, this is a
bit over my head as I'm not the world's greatest coder (understatement of
the year) and my site isn't using cfengine atm (which I'm working on
changing). And hopefully this will all be a moot point when cfengine 2.0
comes out with it's own batch of problems.

Right, well if you don't need cfd, try recompiling it without the -pthread
option and see how that works. Also, please let me know how it goes as I'm
painfully lacking on data about how the port does or does not work.
