    No, it is a conflict between Apple's Software License Agreement for the
    XCode software needed to build 64-bit Mac binaries, and the GNU General
    Public License that GUB, the build system we use for generating the
    binaries downloadable from our web site.
    
    Use of software not allowed to run on non-Apple hardware for building
    the binaries we offer is also arguably incompatible with the GNU
    maintainer guidelines objecting to the promotion of non-free software on
    webpages for GNU software.

Do you believe that it is impermissible for us to offer a binary compiled using 
XCode on lilypond.org?  For example, if Marnen were able to get a 64-bit 
lilypond.app binary compiled using MacStadium and agreed to provide it for 
every release, do you believe we would legally or morally be prevented from 
hosting this binary on lilypond.org.

If you do believe we would legally or morally be prevented from hosting this 
binary on lilypond.org, do you believe we would be legally or morally be 
prevented from providing a link to a download hosted elsewhere?

If I were to develop a website that hosted Marnen's build, do you believe we 
would be legally or morally prevented from providing a link to my website, 
which then had a link to download Marnen's build?

Assuming there is no free version of the software needed from XCode, do you 
believe there is any legally and morally permissible way for lilypond.org to 
point someone to available 64-bit Mac binaries?

I'm asking these questions not to complain or cause problems, but just to find 
out where you think the legal and moral boundaries are for sharing a 64-bit Mac 
binary.  

Thanks,

Carl
