+- Downloading, building and installing GNU Radio and all its dependencies is not a simple task. We recommend to use PyBOMBS (Python Build Overlay Managed Bundle System), the GNU Radio install management system that automatically does all the work for you. In a terminal, type:
 
-$ wget http://www.sbrac.org/files/build-gnuradio
+$ git clone git://github.com/pybombs/pybombs 
-$ chmod a+x build-gnuradio

-$ ./build-gnuradio
 
-This can take a while (up to two hours to complete, depending on your system), and installs the latest versions of UHD and GNU Radio in your system, including all their dependencies. In case you do not want to use the script and prefer to build and install GNU Radio manually from source, follow instructions in http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide
+Configure PyBOMBS:
 
-- Set up some system variables needed by the GNSS-SDR build system:
+$ ./pybombs config 
 
-export PYTHONPATH=/usr/local/lib/python2.7/dist-packages
+You can safely accept the default options but for prefix. We recommend to put /usr/local there. After the configuration, you should get something similar to:
-export LD_LIBRARY_PATH=/usr/local/lib

+gituser = username
+prefix = /usr/local
+satisfy_order = deb,src
+forcepkgs =
+timeout = 30
+cmakebuildtype = RelWithDebInfo
+builddocs = OFF

+Then, you are ready to download and install UHD (the Universal Hardware Driver), GNU Radio and all their required dependencies by doing:
+
+$ sudo ./pybombs install uhd gnuradio
+
+This can take some time (up to two hours to complete, depending on your system), and installs the latest versions of the Universal Hardware Driver (UHD) and GNU Radio in your system, including all their dependencies.

 The full stop separated from "cmake" by a space is important. CMake will figure out what other libraries are currently installed and will modify Armadillo's configuration correspondingly. CMake will also generate a run-time armadillo library, which is a combined alias for all the relevant libraries present on your system (eg. BLAS, LAPACK and ATLAS).
