Titolo: flex is required! Dove trovarlo?

Vorrei istallare un programma che durante il 'make' da errore perché
non trova il comando "flex".
Come e dove trovarlo?
Per comodità riporto sotto l'help per l'istallazione dove accenna al
comando.
Grazie in anticipo, Mario.
GNU flex is required, and lex is not supported (and never will be).
    You *must* use GNU flex and not lex when compiling this package.

Requirements
============
  GNU flex
    GNU flex is required, and lex is not supported (and never will
be).
    You *must* use GNU flex and not lex when compiling this package.
Quick Installation
==================
  ./configure
  make
  make install
  The default installation directory is /usr/local/arts/ (this may
  be changed by using --prefix with configure).
  After installation, you'll want to add the bin subdirectory of the
  installation path (usually /usr/local/arts/bin) to PATH in your
  environment, and add the man subdirectory of the installation path
  (usually /usr/local/arts/man) to MANPATH in your environment.  When
  you run 'make install' successfully, a message will be printed to
  remind you to add these settings to your environment.
 
 
Tested Platforms
================
  This package has been compiled and used at CAIDA on the platforms
  listed below.  This does not in any way indicate the portability of
  this software nor the stability.  It merely indicates what operating
  systems on which this package is relatively easy for CAIDA to
support.
  Note that I'm currently using g++ 2.95.1 on all platforms.  This is
the
  recommended compiler, especially in light of the recent C++ standard
  and STL improvements after g++ 2.8.1 (most of them were also in 
  egcs-1.1.x).
  If you're using another compiler, my odds of being able to help you 
  with problems are slim to none, but that doesn't mean I won't try.

Other Platforms
===============
  There's no reason to believe that this software will not work on
other
  UNIX platforms with g++ 2.7.2.3 or greater.  There's also no reason
to
  believe it will work.  ;-)  However, I have received reports from
the
  field of the following working platforms:
  Operating System	Compiler			Date
  --------------------	------------------------------	------------
  Digital UNIX 4.0B	g++ 2.8.1			Jan  4, 1999
  BSDI BSD/OS 3.1	g++ 2.8.1, libstdc++ 2.8.1.1	Jan 10, 1999
  BSDI BSD/OS 4.0	g++ 2.7.2.1			Jan 11, 1999
Compiler Optimization
=====================
  I've had no problems using 'make "CXX=g++ -O2"' on the "Tested
Platforms"
  listed above, but caveat emptor.  If you have problems compiling
with -O2
  optimization and g++ 2.7.2.3 or greater, please let me know.
