/opt/ros/fuerte/stacks/exploration/explore$ cmake .

/opt/ros/fuerte/stacks/exploration/explore$ rosmake

/opt/ros/fuerte/stacks/exploration/explore$ make

You better use overlays instead of trying to change installed packages in place.

EDIT: (presuming you are on clean ROS installation)

After making overlay workspace with sandbox directory (as described above) do:

$ roscd && cd sandbox

Now you should be in ~/fuerte_workspace/sandbox or wherever you have made overlay.

Next, download exploration stack sources:

$ svn co

Update rosstack and rospack cache:

$ rosstack profile && rospack profile

Make sure that overlaying stack is visible to ROS:

$ roscd explore

This command should bring you to ~/fuerte_workspace/sandbox/exploration.

Now you can edit the sources.

To compile the whole stack:

$ rosmake exploration

And finally to run explore node:

$ rosrun explore explore

In general, it is not a good idea to run node executable directly. So always use rosrun.

Did you add overlay after clean installation of ROS? If not, reinstall ROS and try again.
