It looks as if your TeX installation is broken.
In your list of installed packages, I found some packages
that don't exist in current Cygwin and might interfere with
the other tetex packages:
tetex-beta 20020911-1
texmf-tiny 20020911-1
Try to rerun setup.exe and uninstall
I have been unable to successfully run lilypond 2.0.1 under cygwin.
Previous versions (1.4, 1.6) ran well.
As can be seen in the attached bug.txt file, there appears to be a
problem (in creating fonts?) where TeX crashes, needing an increased
trie size.
Any thoughts?
