No worries, anglophony, as when I first gave the command to install build essential development packages, I put c- instead of -c.
And once again, I learn something new. I've never seen that person's wiki. You must be referring to this page
where mentioned about similar base between Corporate and Pardus regular. And, he or she has his own repo. I'll have to check it out, though there be only a few packages there. See, I wouldn't have known this if you did not have compiling problems.
And yes, I did refer to the configuration log. It can be lengthy, which is why I mentioned the relavant (errors) part. Seeing you needed a header file, I figured you didn't have all the complete build essential packages.
