Well, it's my fault. I fixed a problem with some Linux
versions and when I now read the fine print of the 
documentation, it appears that I used a module 'resource'
that's only available on UNIX systems. 

The patch below should hopefully solve the problem (I'm
not an Python expert so I don't know if this is the best
way to handle the problem).
A side note: why was the setrlimit statement removed 
in 1.5.8?

(The simplest way to solve the problem in your Windows
installation is simply to remove the two lines of the 
script usr/lilypond/bin/ly2dvi.py that containts the
word `resource'.)
