On Fedora Core (4 and 5), I'm getting expansion errors which shouldn't occur:
 
nothing provides /usr/bin/symlinks (this should be provided by the symlinks package, perhaps the system does not currently support file based requires?)
[x86_64] nothing provides libpng-devel (there should be a x86_64 RPM for libpng-devel)
 
Thanks,
