Incompatibility of Perl5.10.0 with MT4.1

I needed a CPAN module "File::Basename 2.76" (It seemed to be included from perl version 5.10.0), so upgraded perl to version 5.10.0.

As a result, MovableType4.1 got an error in its library.

(Got an error: Can't locate object method "configure" via package "MT::ObjectDriverFactory" at lib/MT.pm line 877.)

I removed 5.10.0 and switched it back to 5.8.8.

MT4.1 is not incompatible with perl5.10.0 at this moment.
