`getThreads not available` warning when opening MRO built with conda

[Richard Border]

After building R through the `mro` conda channel and install MKL via the instructions provided by https://conda.io/docs/mro.html, I see the following warning upon starting a new R session:

Multithreaded BLAS/LAPACK libraries detected. Using -1 cores for math algorithms.
Warning messages:

1: In value[[3L]](cond) :
  "getThreads" not available for .C() for package "RevoUtilsMath"
2: In value[[3L]](cond) :
  "getThreads" not available for .C() for package "RevoUtilsMath"

I can confirm that parallelization is working, but it appears to only be utilizing 4/8 cores. Has any one faced a similar warning?

Cheers,
Richard
