I'm guessing you want to take the pod2xxx.PL utility generators out of  
pod/ and put them under cpan/ with the modules they belong to?

None of them will even build on VMS, details below.  In two cases they  
seem unaware that the command-line utility being built will have  
a .com extension, and in the other case (Pod::Parser) it knows it  
wants podselect.com but doesn't know how to generate it.

Pod::Parser seemed closest to workable so I fiddled with it a bit.  I  
got it to build by this tweak to Makefile.PL:

but installing did not do anything with any of the generated .com  
files.  This could be MakeMaker's fault; I don't think I've ever built  
a module that installed a standalone program outside the core, so that  
capability may never have been tested (or may have gotten broken).
