cygwin, lilypond-book 2.6.4 and a font problem

[Maurits Lamers]

Hi all,

I posted this message yesterday, but didn't see any reactions on it, so 
I guessed it may have been overlooked.
If not, sorry :)

The problem is this:

When running lilypond-book with the option --psfonts on a tex file, it 
says that it is unable to extract Aybabtu-Regular from the generated 
eps file.
This results in non-existing, or at least completely unreadable lyrics 
when using dvips.

Is this a bug ?

regards
