If not, can you explain the situation (I am trying to learn).
armci-mpi is indeed statically linked. I wasn't involved with the full setup of the package so I can't provide the full rationale behind it. Sometimes in scientific computing, especially in HPC, static linking is used to ensure that results of a computation are reproducible precisely the same way they were to match published results, bugs and all. Buggy results need to be reproducible. Perhaps that's why. Perhaps we should update it to provide and link against shared libraries. Upstream configure does have the option --enable-shared.
