No, no, that's not an error. The problem here is a library that wants
to be thread safe. Adding -lpthread will just make all binaries that
use this library suffer the burden of mutex lock/unlock even if they
are not multithreaded. That's why on most systems the libc provides
pthread_mutex_lock/unlock etc. stubs which do nothing and everybody
happy. In our case, this is not yet the cast just because libpthread is
not integrated in glibc, but we can use the workaround described above.
