Can not export/import portal framework page?

I made a copy of portal default framework page and made some changes in the copy. Later when I transport all content from dev to QA, I export the customized framework page to a transport package, but somehow it didn't get uploaded and imported in QA. So my question is: is it possible to export and import customized framework page from one box to the other? I searched around help docs and forums, didn't find a certain answer.
