You must patch that, it will try to update /usr/share/applications when 
building the rpm which of course isn't acceptable.

For Fedora, you could just remove the target and run automake; autoconf; 
./configure, given that you run update-desktop-database as part of %install.

However, this should really be resolved together with upstream. If they 
want to keep the functionality, one could possibly:

- Move it from install-data-hook to a separate target such as 
'install-desktop' and let users run this as part of installation into 
system dirs.
- Only run update-desktop-database if $(datadir)/applications is writeable:

Personally, I would prefer the first one. To  mess with 
/usr/share/applications when DESTDIR is set is not really the way 'make 
install' is supposed to work. And updating 
$(DESTDIR)/$(datadir)/applications  just doesn't make sense.

But I'm just a newbie, maybe someone else has a better piece of advice here?
