Rendering using OpenSG - c++

Question

I have a bit of a situation here. I am trying to work with OpenSG. I downloaded the package and installed it as it was instructed in the INSTALL file. Then i installed its system dependent libraries as well. Now i tried to build its tutorial and it shows errors. It says glut is not configured but i enabled the glut library while i configured it and have installed all the dependent packages and libraries as well. I dont understand what the issue is.
The errors shown while trying to make OpenSG tutorial is as follows:
ani#anilap:~/OpenSG/Tutorials$ make

If anyone could help me find a solution to this I would be really grateful.
The makefile for the tutorial is as follows:
# trivial makefile for OpenSG tutorials
# use debug or opt libs?
LIBTYPE ?= dbg
# set the path to the installed osg-config executable here
# if you don't set it, the makefile tries to guess
# e.g. if you installed in /usr/local:
# OSGCONFIG := /usr/local/bin/osg-config
# *****************************************************
# you shouldn't have to change anything after this line
# *****************************************************
# try to guess the OSGCONFIG path

# than one system is configured from one dir. Just for the 1.0

When I tried to configure and compile opensg again and tried to make the tutorial it showed the following error which is slightly different from the previous error. I had encountered this error before but it had changed. The error:

Look at this line:
/usr/bin/ld: cannot find -lXmu
That means that you miss a library on your system. The name of that library is libxmu. You need to install the development package for it. If you are using ubuntu, you can do it using the following command:
apt-get install libxmu-dev
