+***************************************************
+Thanks for installing statsample.
+
+On *nix, you should install statsample-optimization
+to retrieve gems gsl, statistics2 and a C extension
+to speed some methods.
+
+  $sudo gem install statsample-optimization
+
+To use it, on Ubuntu I recommend install 
+build-essential and libgsl0-dev using apt-get and 
+compile ruby 1.8 or 1.9 from source code first.
+
+  $sudo apt-get install build-essential libgsl0-dev
+
