[Bf-committers] Alembic support in Blender

[Jeffrey]

Neither can I. For what it's worth, I have tried building from their 
sources, which gives me a linking error, as well as with 
install_deps.sh, which tells me "getopt: unrecognized option 
--with-alembic" and --with-all does not download or build it.

Also Fedora 20 x64
