MySQL & MariaDB Percona XtraDB Cluster 5.x

I have a fresh installation of FreeBSD 10.2 and I have been trying to install Percona XtraDB Cluster. When I try to compile it from source I keep getting this error:


/usr/local/src/Percona-XtraDB-Cluster-5.6.28-76.1/mysys/posix_timers.c:44:23: error: unknown type name 'sigval_t'
timer_notify_function(sigval_t sigev_value)

Would anyone know how to correct this issue?
