Hi, I am getting the "Can't locate object method "binmode" via package "IO::File" with the Twiki-5.1.4 installed on XP. I also have ActivePerl 5.8.6.811 installed. Anyone else seeting this problem? I checked Upload.pm file, it matches the new updated version. Thanks.

Any suggestion on how to update "CPAN:IO::File" library? When I type install IO:File in Perl Package Manager, I see the there are 4 different choices like IO-File-Cached, IO-File-Lockable, IO-File-Multi and IO-File-String, do i need to reinstall all of them? THanks.
