Current (3.4.1) release do not contain packaged version of development files for gfapi for (at least) debian and ubuntu. Expected: separate packages for libgfapi libs (glusterfs-api ?) and its header files (glustedfs-api-dev ?) in debian wheezy repo and ubuntu ppa. This headers are needed to build qemu with gluster support.
Separating of libgfapi libs is not needed actually, but it seems that to be consistent with fedora/redhat repo layout is a good idea.
I'll look into this. Thanks!
I believe that current Debian and Ubuntu packages now have glfs.h
