PDF files won't open.

I am having a problem when clicking on PDF files - that they no longer will open after I removed the SuSE 7.3 Pro's version of CUPS. When I try to ./configure gimp-print I get the following error message: configure: WARNING: PDF documentation cannot be regenerated! checking for db2ps... no configure: WARNING: PostScript user's guide cannot be regenerated! checking for db2html... no I assume that these two files/libs or whatever they are (db2ps and db2html) are somehow related to CUPS. The important issue is how do I get these two thingys back on my SuSE 7.3 Pro install? Cheers, Brian
