Manjaro error during installation (undefined pthread_yield)

[ffuentese]

I'm having the following issue installing inferno:

/usr/bin/ld: kproc-pthreads.o: en la función `osyield':
/home/ffuentes/inferno/emu/Linux/../port/kproc-pthreads.c:214: referencia a `pthread_yield' sin definir
collect2: error: ld devolvió el estado de salida 1
mk: cc -c -m32 ...  : exit status=exit(1)
mk: echo "(cd $SYSTARG; ...  : exit status=exit(1)
mk: for j in ...  : exit status=exit(1)

I know this is very old but I really wanted to try it!
