This was the whole point. AdminMisc is still quite useful but not maintained any longer and annoying to recompile (it deals with the Windows API afterall). If you want to upgrade to Perl 5.10 you won't be able to find a PPM so without a fairly old compiler and the process I posted you would be out of luck
OK, I have received a lot of mail since posting this so decided to add support for 5.10 to Roth's existing ppd and host it on my site at http://www.ramtek.us.
