glib20 build problem.

[Adam K Kirchhoff]

When trying to build /usr/ports/deve/glib20:

checking for pthread_create/pthread_join... no
checking for pthread_create/pthread_join in -lpthread... no
checking for pthread_create/pthread_join in -lpthread32... no
checking for pthread_create/pthread_join in -lpthreads... no
checking for pthread_create/pthread_join in -lthread... no
checking for pthread_create/pthread_join in -ldce... no
configure: error: I can't find the libraries for the thread implementation
                posix. Please choose another thread implementation or
		provide information on your thread implementation.
		You can also run 'configure --disable-threads'
		to compile without thread support.


Any ideas (other than disabling thread support)?
