pod2pdf print blank page

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

I installed App::pod2pdf from CPAN to a local library ~/mylib/lib/perl5 and tried to use it from the command line like:

 perldoc -f each | pod2pdf > each.pdf

and bash returns that it can't find the pod2pdf package...

Then I installed pod2pdf from Ubuntu's software center, and tried the same command line input, this time it created a each.pdf file. But when I open it I only saw a blank page with 'STDIN' on the right upper corner and 'Page 1' on the bottom.

Could someone please tell me how to make it work?

Thank you very much!!

    This is because text returned by perldoc is no more POD, but is just plain text. For example:
    $ head /usr/share/perl/5.14/pod/perldoc.pod =head1 NAME perldoc - Look up Perl documentation in Pod format. =head1 SYNOPSIS B<perldoc> [B<-h>] [B<-D>] [B<-t>] [B<-u>] [B<-m>] [B<-l>] [B<-F>] [B<-i>] [B<-V>] [B<-T>] [B<-r>] [B<-dI<destination_file>>] $ perldoc perldoc | head PERLDOC(1) User Contributed Perl Documentation PE +RLDOC(1) NAME perldoc - Look up Perl documentation in Pod format. SYNOPSIS perldoc [-h] [-D] [-t] [-u] [-m] [-l] [-F] [-i] [-V] [-T] [-r] [-ddestination_file] [-oformatname] [-MFormatterClassName]
    Try perldoc -u <whatever> | pod2pdf instead (option -u makes perldoc show just raw Pod source).
    Sorry if my advice was wrong.

      I do not have pod2pdf, but I can confirm that the following variant seems to work nicely on my Windoze system:

      perldoc -u -f each | pod2html > junque\each.html
      Thank you very much, aitap! It worked this time =D
