Error while building unifyfs version 0.9.2 using spack

System information

Type	Version/Name
Operating System	ubuntu
OS Version	18.04
Architecture	x86_64
UnifyFS Version	0.9.2

Describe the problem you're observing

The latest spack packages have a new version of mochi-margo 0.9.10. In this version, the libraries are renamed. The current build of unifyfs version 0.9.2 works with mochi-margo 0.9.6. However, the docs mention only mochi-margo which defaults to latest. Can you please update the doc to reflect this version? For your reference, here is the spec I used for a successful installation of [email protected] with spack version 0.19.0.dev0.

NOTE: I have the SDS repo (https://github.com/mochi-hpc/mochi-spack-packages) from mochi developers as I use thallium for my projects. They have conflicting packages between spack builtin and SDS repo. Please add that warning note in the docs for users.

Describe how to reproduce the problem

To reproduce checkout the latest spack packages (I tried with commit 1c0bf12e5b21de3d77af2b1025479d30c4c94400) and install unifyfs.

Error

We see that configure is not able to find margo lib. It has been renamed from libmargo.so to libmochi-margo.so.
