Mozilla needs libgtk-x11-2.0.so.600

[Malcolm Fitzgerald]

I'm setting up a new machine and getting this error from Mozilla:

/libexec/ld-elf.so.1: Shared object "libgtk-x11-2.0.so.600" not found, 
required by "mozilla-bin"


locate shows me that I've got "libgtk-x11-2.0.so.0"

where / how can I get *600 ?
