for ActiveState Perl 5.6 at least.  I am offering this from my 
experience this morning with an urgent need to install and use the 
Date::Calc module (why on earth would that be left out of a default 
install?  It seems to me to be such an obvious function to make up for 
the Windows cmd shell lack in that regard) to get an overdue project a 
bit further along.  Since it took me over an hour to piece together 
clues from various Perl doc resources, and google searches, I hope this 
how-to is a bit of giveback to the Perl community (esp newbies/dabblers 
like me ;-).  Any corrections and enhancements are certainly welcome!

This was necessary for installation on a server behind a firewall (and I 
do not care to risk my job by violating security policies in trying to 
"find" a way to proxy out to the ActiveState repositories - and hoping 
this much "initiative" is not in violation either ;-).

What worked for me:


1. Download/unzip the Perlmod package to a dir WITHOUT SPACES IN ITS 
PATH LIKE "DOCUMENTS AND SETTINGS".  ppm does not seem able to "ignore" 
the spaces (even with the surrounding quotes), and thus uses them as 
command separators.

2. Run "ppm":

PPM> set repository Local C:\sysfiles\perlmod

PPM> set

Commands will be confirmed.
Temporary files will be deleted.
Case-insensitive searches will be performed.
Package installations will continue if a dependency cannot be installed.
Tracing info will not be written.
Screens will not pause.
Query/search results will be verbose.
Current PPD repository paths:
         ActiveState Package Repository: 
soap://www.ActiveState.com/cgibin/SOAP/ppmserver.plex?class=PPM::SOAPServer
         Local: C:\sysfiles\perlmod
Packages will be built under: C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp
   [Guess I could have used the 8.3 munged dir name as above?]

[NOTE:  get rid of the ActiveState web repository setting!!!]

PPM> set repository --remove ActiveState Package Repository

PPM> set

It appears from "help set" that "set save" would make my mod permanent, 
but there might be another "policy issue" there...

My perl program worked like a champ with this module after this update.
