perldoc perlvar has this to say:

Due to an implementation glitch, the $SIG{__DIE__} hook is
called even inside an eval(). Do not use this to rewrite a
pending exception in $@, or as a bizarre substitute for
overriding CORE::GLOBAL::die(). This strange action at a
distance may be fixed in a future release so that $SIG{__DIE__}
is only called if your program is about to exit, as was the
original intent. Any other use is deprecated.

The key line is "even inside an eval()". Log::Agent is not found in the eval, and perl calls your DIE hook.

Not knowing more about what you are trying to accomplish, I can only suggest moving the begin block after the use Storable; line.
