I can check with debian-release, but that'll be hard.

It is a bug in the build process.

€ nm -D libspeechd.so.2.2.1 | grep pthread 
                 U pthread_cancel
                 U pthread_cond_destroy
                 U pthread_cond_init
                 U pthread_cond_signal
                 U pthread_cond_wait
                 U pthread_create
                 U pthread_exit
                 U pthread_join
                 U pthread_mutex_destroy
                 U pthread_mutex_init
                 U pthread_mutex_lock
                 U pthread_mutex_unlock

libspeechd.so uses pthread_create, so it needs to explicitly link
against the library that provides it, i.e. -lpthread. libc provides a
couple of stubs for things like mutex_lock & such, but clearly not for
pthread_create :)

It works by chance for applications which happen to use pthreads already
(and thus get the pthread_create symbol), but not for applications which
do not use pthreads at all.
