File::Copy module not loaded, causes crash in configure.

[Sat Jun 23 23:33:19 2007] configure: Undefined subroutine &File::Copy::copy called at /home/twikidev/lib/TWiki/Configure/Checker.pm line 271.

Fixed in SVN checkin, through dynamic require/import.

I suspect my home server may be flaky, so it would be good if someone else could reproduce this.

I've noticed a couple of places where there is no explicit use Module though - it may be that some Perl versions implicitly load the module when it's referenced, but that's news to me...

-- TWiki:Main.RichardDonkin - 25 Jun 2007

I wrote a script to audit all the perl modules to ensure that modules are require ed wherever they are used. It's in tools/check_requires.pl. I just ran it again, and updated all the modules it highlighted, but none would account for this error.

Note that you don't need the import, as the reference to File::Copy is fully qualified, and therefore in the root namespace. You only need the import if you want to pull symbols into the namespace of the calling module (a bad practice, IMHO).
