Lyric tie

[Francisco Vila]

Hello, I have been searching a lot and still can not find a solution
for my lyric ties.  I obtain very misplaced ones and I know that a
font like DejaVuLGC installed should do the trick in my Ubuntu system.
My problem is: I have it installed, how do I force lilypond to use
that font?

\version "2.13.40"
\relative c' {
        r4 f e d | c2 c
}
\addlyrics { Buon gior -- no~al mon -- do. }

It looks all right in evince, but prints very misplaced on printer and
looks the same in jedit/lilypondtool.

Thanks!
