Hello,

I’m trying to configure MPI.jl. I installed OpenMPI according to these instructions:  
[https://wiki.helsinki.fi/display/HUGG/Open+MPI+install+on+Mac+OS+X](https://wiki.helsinki.fi/display/HUGG/Open+MPI+install+on+Mac+OS+X)

I’ve confirmed that `/usr/local/bin` is in $PATH. Then I followed this page to try and configure MPI:  
[https://juliaparallel.github.io/MPI.jl/stable/configuration/](https://juliaparallel.github.io/MPI.jl/stable/configuration/)  
but when I run  
`julia --project -e ‘ENV[“JULIA\_MPI\_BINARY”]=“system”; using Pkg; Pkg.build(“MPI”; verbose=true)’

It gives me the error:

```julia
   Building MPI → `~/.julia/packages/MPI/biSVL/deps/build.log`
[ Info: using system MPI
ERROR: LoadError: libmpi could not be found
Stacktrace:

└ @ Pkg.Operations /Users/julia/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.5/Pkg/src/Operations.jl:949

```

It seems others have this problem and fix it by adding something to the /.bash\_profile like

```julia
export JULIA_MPI_PATH=/usr/local/

```

But I am still getting the same error when I try to build MPI. I’m not sure if the symbolic link is pointing to the right folder? I’m not sure what I’m looking for.

Any help would be appreciated! Thanks!
