I also ran into the same error message while compiling the araisrobo branch
of LinuxCNC.

It could be reproduced; please follow the "Building the araisrobo branch
wiki",
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ArtekBranch
The configuration is set for "simulation without X11":
./configure --enable-simulator \
--enable-build-documentation=no \
--disable-gtk --without-x
The error messages occurs when
Compiling emc/rs274ngc/interpmodule.cc

The araisrobo branch could be compiled and running with the 12.04 image
obtained from http://elinux.org/BeagleBoardUbuntu (boot with SD).
I don't have above error while compiling "arm335x-hal-pru-module".
