I am getting this error when running ./bin/spack install stat: on my local machine:

llvm requires binutils variant +plugins, but spec asked for ~plugins

What packages should I install/edit here?

[lee218llnl]

Was this a recent checkout of spack? Can you do a git pull in your spack directory and see if that fixes it? If not, then can you please submit an issue to the spack github project and assign it to me? This is more of a spack dependency issue that a STAT one. Thanks.

[lee218llnl]

I can reproduce the problem. You can work around this with:

./bin/spack install stat ^binutils+plugins

[lee218llnl]

@abhaasgoyal I submitted an issue to the Spack project. Please let me know if the workaround works for you in the meantime.

[abhaasgoyal]

@lee218llnl it's installing successfully now, this workaround works for me as of now.. thank you very much for clarifying.
