I have Raspberry Pi, realtime kernel in it and machinekit 2.7-0 package. Boost version is 1.55-0.

What to check, since the machinekit does not find the boost?  (and therefore configuration script fails)

Linux raspberrypi 3.18.11+ #781 PREEMPT Tue Apr 21 18:02:18 BST 2015 armv6l GNU/Linux

configure: error: boost::python is required to build LinuxCNC

pi@raspberrypi /machinekit/src $ dpkg -l | grep boost
