(Q)how to use perl in cygwin-b20?

[Okehee Goh]

Hi,
 
I'm using cygwin-b20(I don't know the version of cygwin 
installed in my computer. 
The folder structure for this package is "C:\cygnus\cygwin-b20\H-i586-cygwin32\bin".
 
I need to use perl.  However, the cygwin I have doesn't 
include perl.
So, should I install perl-5.6.0-RCI on the current 
cygwin?
To do that, I need to install RPM first of all. 
The procedure looks complicated.
 
Is there any other way to upgrade everything at just one step 
without paying to buy software?
 
Sorry if this question is too egoistic.
 
Okehee
