I followed the WordPerfect for Linux FAQ, downloaded several libraries and got it working at some point a few years ago. Was not impressed with this version of WordPerfect and it was not nearly as useable as on Windows. I really like WordPerfect, but for using it on Linux, I'd personally go with one of the DOS versions over the Linux version. A lot of things just seemed to work better with the DOS version, including whatever passes for WYSIWYG features and font handling. There are also several free add on utilities you can get for the DOS versions, like standalone dictionary front end and ways to update the grammar check system.
There's an interesting article on running old DOS word processors here:
http://www.downloadsquad.com/2005/11/25/free-file/It includes a link to freely download Word for DOS.
Unfortunately, WordPerfect for DOS isn't free for download, so if you don't have a copy, you're kind of stuck. However, bits and pieces of it were released. Some references here:
http://short.stop.home.att.net/freesoft/txtedit1.htm#wpedithttp://www.columbia.edu/~em36/wpdos/At one time WordPerfect did not run in DOSEmu, but that was a long while ago, so I assume it does now. It does run in DOSBox and I run it that way. Note that DOSBox does not have printing support and was not meant to print. There is a patch to DOSBox that will let you print to a serial device. When I want to print WordPerfect documents from DOSBox, I use the print to file feature. Once the document is saved to file in postscript format, you can use Ghostscript and whatever front end/viewer for ghostscript that you prefer to actually print the file. Takes some work to print, but if you want a capable word processing program (which can handle laying out books, cards and more) and don't have a system with the resources to run Open Office or a latex based application, using a good quality DOS word processor in DOSBox is a convenient alternative.
