Because you have flex, not lex.

Flex is free but non-GNU lex. See:
http://www.gnu.org/software/flex/
which therefore points to sourceforge.  The problem, from the
information you have given as I see it, is that your Makefile is
looking for lex, when it should be looking for flex.  You'll need to
see how it is used in the Makefile.
