Despite your insistence on it, studying spec files from other distros is not how to learn to package for PCLinuxOS.
And I don't understand why you continue focus on "other distros specs" instead of "converting to pclinuxos format".
I gave you the skype 4 example, the dependency problem that I had I resolved it looking in PCLinuxOS spec's format, not in Mandriva spec's format.
I never intended to studied "others distros specs", I just tried to grab a "other distro specs" and converting to PCLinuxOS format, and I did with skype 4, maybe is not 100% but it is working. If you think this is a bad idea, you should explain why converting shouldn't be used instead of saying that studied "other distros specs" are wrong.
In the RPM manual the 1st option to make a PCLinusOS spec file is to grab a already created one from other distro and convert it.
