Ebuild showing the problem

Hi,

portage doesn't support ExternalProject's ExternalProject_Add feature. I have my own ebuild for kdenlive live ebuild (it was in the kde overlay but recently was gone). The CMake tries to download external project. While running it under portage supervision ('emerge kdenlive' or 'ebuild kdenlive.ebuild compile') the external project is not downloading and compilation breaks. When doing it manually (in the build folder prepared by portage in the earlier step) by running 'make' it works just fine.

Portage way:

Manual way (the file was downloaded earlier):

I attached the ebuild which should reproduce the problem.

Try setting RESTRICT="network-sandbox" in the ebuild.

Ok, it fixed the problem. Thanks. Didn't know this trick.
