That's correct that FindBin doesn't work under mod_perl. But the reason is
different. It doesn't work because its invocation happens during the load
of the module itself and as any other module under mod_perl it's loaded
only once per process.
It has nothing to do with BEGIN block.
A possible workaround is to mess with %INC:
delete $INC{FindBin};
use FindBin;
Anyway, thank you for this spot. I've offered this solution in the guide
and didn't know it has a problem. I'll update the guide.
