Welcome to the Packagers section of the forum. Sorry for the delay in replying but as I'm sure you know we are all quite busy at the moment
I've had a look at your SRPM and of course it builds and runs fine so well done on that!.
No real mistakes but if you are interested in packaging for PCLinuxOS there are some guidelines in the sticky threads of this forum section which help ensure that we produce consistent high quality packages. Referring to this
entry, the name of the spec file should be pclos-dstat.spec
and the version in the changelog entry should be 0.7.2-1pclos2012
Other than those 2 minor points it looks fine to me. We look forward to seeing some more from you.
