after some reading and some tests I'm pretty satisfied of pp tool.
I converted my switch in an if/elsif series as advised.
Then I added some modules with -M option
(Net::SMTP:TLS and MIME::Lite).
So I ran some test programs with some satisfaction.
Now I plan to use Simple::XML to read a config.xml file.
pp doesn't find SAX.pm, so I linked it with -M option, but I have still another error:
Can't locate unicore/Heavy.pl in @INC
I have tried to link Heavy.pl through -M option, but... nothing to do... The program is still searching Heavy.pm
So I searched over the web (Googled) and I found that thread:
it seems related to my problem
(I have too strawberry perl 5.12, etc.)
but not understood much about it...
It seems there is a patch for Module::ScanDeps...
the problem is that I don't know how to install that patch...
(I have to simply insert it in Module main folder, and the make, make test, make install?)
Thank you for your help
