AH Ah ah.....  THANKS -- I should have thought to grep for it

Swaroop -- could you would you in the plane write a little essay
on why would we want to use dgesvd as the default for Hyperalignment?   

We might like then add 'auto' setting for svd which would choose
dgesvd if available and regular numpy's svd if not...  Ideally imho I
would prefer to have numpy's implementation as the default if in 99% of
the cases they provide comparable results at comparable speeds and
dgesvd as the workaround for some tricky cases.

ok, Kiefer -- quick workaround  would be to initialize your
Hyperalignment with alignment=Procrustean()  without custom svd
