Turns out that Conrad now uses zgesdd for a divide-and-conquer SVD on complex
data, and R's libRlapack does not have it. 

We're trying to figure out how to best address this.  In the meantime, and
particularly if you use a complete external Lapack library (rather than R's
stub), or if you don't use complex-valued data, feel free to grab 0.3.930.0
from the URL above.
