-- Hi, there is a build failure on ppc64el due to the fact that the code enabling altivec specific parts makes confusion between MacOS and Altivec existence. https://buildd.debian.org/status/fetch.php?pkg=dhewm3&arch=ppc64el&ver=1.4.1%2Bdfsg-1&stamp=1485535734&raw=0 Thus the SIMD code uses ppc_intrinsic.h api which is not available in gcc on Linux. I added some ifdef to detect MacOS and skip that code. Here is a debdiff in attachment. F.
