  Just as an alternative to stennie's above, here's one that uses a built-from-source perl, rather than ActiveState's

  You'll need this zip file: http://www.fireartist.com/tmp/vanillaPerl5.8.7.zip [fireartist.com] (41.5 KB)

  Unzip the file in c:\ it'll create a folder named c:\vanillaPerl5.8.7
  Just follow the instructions in c:\vanillaPerl5.8.7\build\installer.txt

  This is a very basic installation including perl5.8.7,

    A perl-level issue to be aware of is: you can't use cpan to upgrade a core module such as CPAN or File::Spec because MSWindows won't let a .dll file be overwritten while it's in use. (I know there's people are looking at this issue).

    Its not a perl level issue at all. On win32 you can't delete open files. Period. Any installer will end up confronting this issue. Its the reason for the dreaded "you must reboot your machine" messages that are so well known in the Windows world.

    Some install techniques on windows are more suceptable to this issue than others, with Module::Build and CPAN particularly so as they use the things they are installing to do the install. EU::MM modules are less so as the install process is actually done by nmake.exe which means that the installer is less likely to have open the same files as are being installed. So as an example often with a EU::MM install if it fails you can exit out of CPAN and go to the build directory and run 'nmake install' and it will work fine as perl is no longer running and keeping those files open.

    So IMO this shouldn't be characterized as a bug. Its a general win32 annoyance that is difficult to work around no matter what you do.

      Thanks for the clarification ++
      
      Maybe CPAN / M::B could get round it, if libwin32 is installed, by adding a registry entry in the relevant 'run once' key, and asking the user to reboot.
      
      I'd personally find it quite amusing seeing cpan say "installation finished, please reboot to continue"!
      
      I suppose a problem would be if it happens when installing a prerequisite. Would it be sufficient for cpan to say, "please reboot, then run 'install Foo' again", rather than try to remember the state it was in?
