The package depend on libelfin, <URL: https://github.com/ccurtsinger/libelfin >, to work, and will fail to build without it.
Surprisingly enough, the build will clone the git repository and make the source available, so the problem is not too abvious when building the code for the first time. In addition, the build will download and build several example programs, but I suspect those failures will not be a fatal problem in the build process. -- Happy hacking Petter Reinholdtsen
