It looks like some floating point extension are not properly detected on ppc64le (gxx 13.2):

Can you try running from develop? I fixed a few ppc64le related issues since release, and locally everything seems fine with both long double ABIs.

Hi Matt, sure I can add patches to the build. Were you referring to 100473b ?

[mborland]

Yes. #193 will apply as well if you need quadmath support on ppc64le.

With 100473b we manage to build our Conda recipe for all platforms. Thank you!
