Compiling arts in -CURRENT without -pthread



Hi,

I'm trying to compile arts (audio/arts) in -CURRENT. I replaced -lpthread with 
${PTHREAD_LIBS} in the ports' configure script. This makes it recognize -lc_r 
correctly, and it also uses that when building the port.

However, after some time, the port will fail with these error messages:

How can all these pthread_* functions be undefined when it is linking against 
-lc_r?
