[TxMt] tiny improvements for perlmate.rb

[Alexander Ross]

James,

I tried this out but couldn't get it to work.  $@ wasn't set when the  
END block was called.

The good news is if we are in an eval block, exception_handler::die  
can call Carp::croak[1].  Which "dies of errors (from perspective of  
caller)".
