Thanks perrin, esper and the anonymous monk who have offered ideas for how to unravel this issue. In the morning, after some sleep I will try adding the Devel::Trace to the mix. In the mean time I used my ->log() method to dump @INC, %INC, %ENV and %::.

I have no idea what '%::' is about, and it does not seem to be documented in my pocket reference, either. %INC includes both my base class and the modules from which they import those ':all' tags (among many other dependencies). I commented out the use ::Account qw( :all );, in favor of a use ::Account qw( _GenerateAccountSummary );. But I still am getting this same error -- that it Can't locate object method "_GenerateAccountSummary" via package.

What is '%::'? And what should I be looking for in its content?

Do these results suggest anything to you folks? I'd really love to get past this issue. I have a few issues besides this one left to iron out, and was hoping to unveil this application when I present at a conference next Thursday. I was distracted by other work today, but hope to return to this issue in the morning.
