"cc" is usually used to compile C programs. Use the command-line tool 
"c++" (or "g++") instead for C++. "cc" will determine that you are 
compiling C++ code, but it will not add the standard C++ library (-lstdc++).

Add the following line to your extconf.rb file:

   $LIBS << " -lstdc++"

Before the call to "create_makefile"!
