Bad.  You are done at this point.

Hi Marco,

You are missing the flex package, and thus the "flex" command, on your 
system.  Flex is a lexical parser (classic name "lex").

You didn't say what your host's distribution is.  If it is debian, you 
need to install the flex package.  RH/SuSE may name their package 
differently (probably not).
<http://packages.debian.org/search?keywords=flex&searchon=names&suite=all&section=all>
