I have just built cinelerra on CentOS 5 x86_64 and thought I should share my notes here for people who need it but cannot wait for the package to become available on rpmforge/dag. - Install the src.rpm for FC6 - Edit the .spec file and change the line BuildRequires: OpenEXR-devel to BuildRequires: openexr-devel - Create a symlink: ln -s /usr/include/OpenEXR /usr/include/openexr - Run rpmbuild You need to have all devel packages required. The main problem I encountered was that the FC6 version wants the OpenEXR package and the one I could find for CentOS was all in lowercase. Then during the compilation, it refers to /usr/include/OpenEXR thus the symlink. I don't know the exact consequences this modification would bring about. For now, the rebuilt rpm installed on my system without a hitch and the program runs well. Akemi
