Yes, this works, plus (if nothing provides the original string) i start to 
replace dashes for '=' from right to left. I can't think of any other way how it 
could fail now, but still if you want to install by name only, you can force it 
with --name option (although this way zypper chooses the version to install, not 
the solver).


But still, isn't this a bug?

$ zypper what-provides ghostscript=x11
Reading installed packages...
S | Repository | Type    | Name                | Version   | Arch
--+------------+---------+---------------------+-----------+-------
i | @System    | package | ghostscript-library | 8.15.4-17 | x86_64
v | factory    | package | ghostscript-library | 8.62-4    | x86_64
v | factory    | package | ghostscript-library | 8.62-4    | i586

There should be no providers of ghostscript=x11 or?
And similarly for libldtl=3.
