Jonas, GhostPDL supports many input formats, not only PCL. See


Especially you can feed in PWG Raster and many different types of 
images, which all do not need any fonts at all. So creating a Debian 
package of GhostPDL even makes sense if PCL input does not work due to 
lack of included fonts. First, PCL as input is rare, probably it is much 
more made use of the other input formats. You also can tell in some 
README file that for full PCL input support the user needs to download 
some non-free fonts and from where to download them.
