Because F9 is to be released shortly, it sounds like you will start the F10
packaging effort for CMake-2.6.0 quite soon.  But as soon as that is done,
then I assume you should have no problems packaging a version of PLplot that
build-depends on CMake-2.6.0 for F10.  Is that a correct assumption?

Similarly, the cmake 2.6.0 packaging effort is already underway in Debian
experimental, and Andrew and Rafael would have to wait until that package
got promoted to Debian unstable before they could start packaging a PLplot
version that build-depends on CMake 2.6.0.

I feel strongly that packaging is a really important way to promote PLplot
so I don't want to make life difficult for the Plplot packagers. Therefore,
I would be happy to hold off making the CMake version bump until you were
satisfied with the cmake-2.6.0 packaging for the pre-release version of F10,
and cmake-2.6.0 got promoted to Debian unstable.  I suspect both those
events will occur substantially before 6 months from now, but we will see.
