Dear coinbrew developers,
currently compiling the master branch of Cbc with the master branch version of coinbrew following these instructions fails on a Debian GNU/Linux 11 system. There is an error while building Clp master using MPI, namely

compilation terminated.

Error: Build failed, see error output above

In contrast, compiling older versions of Cbc, e.g. version 2.10.5 or 2.10.8, works fine using the master branch version of coinbrew.
Moreover, the old version 1.0 of coinbrew works well for the current master of Cbc besides the known incompatibility of MUMPS and a gcc newer than version 10, see e.g. #47 and the references therein (fix: add option ADD_FFLAGS=-fallow-argument-mismatch).
Could you please check? Thanks in advance!
