 Thank you, yes if I rebuild ushare and add -lpthread, it works
 properly then. It appears as though the ushare port's Makefile is
 explicitly not adding -lpthread for 7.0:
 
 .if ${OSVERSION} < 700042
 CFLAGS+=    ${PTHREAD_LIBS}
 .endif
 
 I don't know the reasoning behind that, but I'll submit a PR to the
 ushare maintainer to have this fixed.
 
 Thank you very much for your time! I appreciate your help.
 
 Regards,
 Josh
