I have been trying intel mkl and icc compiler instead, with no luck. I
run into the same problem during setup as reported here:
Sigh. I guess I should not get into these matters anyway; I am just a
simple and humble user...
As far as I understand the Ubuntu atlas problems have been found for
complex types, which I don't use except for fft. I guess I'll continue
to use the ubuntu libraries then and hope for better days in the future.
