The PerseusDL version of Morpheus doesn't build, in part because of a missing bin directory. However, creating that directory by hand fixes that problem with the build. In the Alpheios fork, the bin directory exists and has been populated with a bunch of Linux binary executable files. This is not a great solution to the problem. It will not work for people on other operating systems, and it also isn't really a viable solution for Linux, since Linux does not maintain binary compatibility such that a binary compiled on one machine can just be copied to another machine and expected to run. It will work in some cases (and did on my Linux Mint box), but will not work in general. Normal practice in a version control system would be just to commit source code to the repo, not binaries. Maybe there is more to this problem than I'm aware of, but as far as I know, all that is needed is for the directory to exist. It's true that git, by design, does not allow an empty directory to be created in a repository. However, one can get around that simply by putting a README file in the directory that says something like "This is a placeholder for the initially empty directory."
