Lyrics spacing with lilypond 1.6.4

[Alois Steindl]

Hello,
this week I tried the cygwin port of the new version 1.6.4 with a little song.
Since the letters of the lyrics overlap each other, I assume that I have to 
set some flag to change the spacing rule (from note-length proportional to 
(maximum) word-width).
Is there any flag for archieving sufficient space (except placing many breaks, 
which the yields very large space for long notes with short text)?

Best wishes
Alois
