I know "some" (eg rstan) have completemented the BH package with local
headers when BH was missing what they needed (as BH grew, I think we by now
added all they need).  So you could just do that, being careful to stick with
the same version.

Or would Yixuan's RSpectra help?  https://cran.r-project.org/package=RSpectra
