 I try to install ettercap but during configure I get:

 checking return type of signal handlers... void
 checking for vprintf... yes
 checking for _doprnt... no
 checking for library containing pthread_create... none required
 checking whether gcc accepts -pthread... no
 configure: WARNING: ***************************
 configure: WARNING: * PTHREAD ARE REQUIRED !! *
 configure: WARNING: ***************************

 But I suppose library is installed:

 MacBook-Guido-2:ettercap-NG-0.7.3 guidov$ port installed xorg-libpthread-
 stubs
 The following ports are currently installed:
   xorg-libpthread-stubs @0.3_0 (active)
