Source: openmpi Followup-For: Bug #971669 As far as pmix_ext3x.so goes, the other arches are picking it up from --with-pmix=/usr/lib/<arch>/pmix2 (i.e.--with-pmix=$(LIBDIR)/pmix2) added to dh_auto_configure in the PMIX variable in debian/rules.
This external pmix is excluded from armel and mipsel by NO_PMIX_ARCH:= armel mipsel On your abel build, did you change the setting of NO_PMIX_ARCH? /usr/lib/arm-linux-gnueabi/pmix2/ is available for armel (and mipsel). Was breaking it breaking openmpi on those arches? Not sure if that explains why _Get_version is undefined in mca_pmix_pmix3x.so, but it might explain why _ext3x.so isn't being built on the buildd.
