[PHP] A problem under Solaris

[Emiliano Marmonti]

Hello all

  I´m trying to compile PHP 4.0 under Solaris 8.0 - SPARC 250. When I try to configure 
using the appropiate script, it test for the existence of one package called lex and 
another called flex, both couldn´t be found and the script can´t continue. Anybody has 
be in the same trouble? Any idea? What are those packages?

Thanks in advance
Emiliano
