Hi,  
I am trying to install ruby-shout(used to serve audio to icecast  
server) .I have libshout,vorbis and liboggz  
But I get this error

ERROR: While executing gem … (RuntimeError)  
ERROR: Failed to build gem native extension.  
Gem files will remain installed in  
/usr/lib/ruby/gems/1.8/gems/ruby-shout-2.1 fo  
r inspection.

Results logged to  
/usr/lib/ruby/gems/1.8/gems/ruby-shout-2.1/ext/gem\_make.out

I am not sure what the "failed to build native extension " means.  
Any ideas  
vivek

That means the ruby-shout gem comes with some C code. The gem  
installation was trying to compile that C code but the compilation  
failed for some reason. That reason is shown in that gem\_make.out log  
file.

Usually the problem is that you’re missing some C libraries. In some  
GNU/Linux distros, it’s common that you’re missing a C compiler  
altogether because it’s not installed by default.

The gem you are trying to install contains a piece of C code that  
needs to be compiled.  
You are missing either the compile environment (gcc, make, etc., if on  
debian/ubuntu: apt-get install build-essential) or some of the  
libraries the extension is dependent on (maybe you need to install the  
dev package of the library - with headers and such).  
Or you are experiencing another error. See the log for details.
