install groovy from source fails at pcl

edit

Hi, I'm trying to install groovy from source on a Gentoo laptop using instructions from here:

www.ros.org/wiki/groovy/Installation/Source

It fails while building the point cloud library. Please help on how to proceed.

Thanks.

The command I'm using to build is:

./src/catkin/bin/catkin_make_isolated --install-space /opt/ros/groovy --cmake-args -DSETUPTOOLS_DEB_LAYOUT=OF

This is the first error it threw up while building the pcl package:

[ 17%] Building CXX object examples/common/CMakeFiles/pcl_example_check_if_point_is_valid.dir/example_check_if_point_is_valid.cpp.o

But then it goes on and then breaks down completely here:

Reproduce this error by running:
==> /home/ro/ros_catkin_ws/devel_isolated/nodelet_topic_tools/env.sh make -j4 -l4

Command failed, exiting.
