See at http://www.ieeta.pt/~tos/TeX.html Tomás Oliveira e Silva's  
bundle pt_language. If his instructions seem too complex, just put in  
your preamble

\usepackage[portuges]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}%% or [latin1]
\makeatletter
\DeclareRobustCommand{\pt at hyphen}{\ifmmode_\else
   \nobreak\hskip\z at skip\discretionary{-}{-}{-}\nobreak\hskip\z at skip\fi}
\catcode`_=\active
\let_=\pt at hyphen
\makeatother

and type viram_nas, empenharam_se instead of viram-nas, empenharam-se.


Best,
