I just grabbed a copy of Parse::Lex and had a quick look at it.  It's 
pretty much Lex done in Perl, while Parse::Yapp is ditto for YACC.  
Although the two can operate in mutual exclusion of each other, they
do go together like, er, Lex and Yacc (they even wrote a book about 
them :-), so it seems sensible to include them both. 

Parse::RecDescent is a different beast altogether and there's 
plenty of time when you might choose one over the other(s).  I'd 
say include all 3.
