The "too big" messages are just warnings caused by one of the modules on which WWW::Myspace depends. They're harmless, but to make them go away see the "date.patch" file included at the root level of the WWW::Myspace distribution for a fix.

This info will be included in the KNOWN ISSUES section in the next release (0.61), which also requires WWW::Mechanize 1.20, which should fix the "stack_depth" error.
