Hi Mark (and all)

Thanks for the response. I ran ./configure --disable-threads this time. ./configure went fine but again upon doing Make I have received a new error:

this continues for a long time and then I get the error at the bottom:

looks like a different set of errors here. Do you think it might have to do with using FFTW-3.3?

Yes. Configure thought it found FFTW3, but now you can't link to it. See the general installation instructions for the right kind of approach.
