(ITS#8034) lmdb-0.9.14 | Undefined symbols for architecture ppc: "_posix_memalign" referenced from _mdb_env_copyfd2 | ld: symbol(s) not found for architecture ppc

Full_Name: Daniel Ibn Zayd Version: openldap-2.4.40-r3 OS: PPC URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (166.84.1.2) This is a followup to a previous ticket. Based on what I learned from that, I went ahead and tried to install the latest openldap on Gentoo Prefix. It pulls in lmdb-0.9.14 which I understand now to be the preferred database backend over db, for example. I successfully fixed one PPC error, replacing -soname with -install_name (ld throws an error here), but I am left with an error having to do with _posix-memalign: Undefined symbols for architecture ppc: "_posix_memalign", referenced from: _mdb_env_copyfd2 in mdb.o ld: symbol(s) not found for architecture ppc collect2: ld returned 1 exit status Over at MacPorts, they are recommending disabling mdb, but this doesn't seem to be a real fix: http://trac.macports.org/changeset/130560 The better fix I think would be to test for _posix_memalign, and fall back to valloc on older Macs. In terms of C preprocessor macros, I believe "powerpc" and "PPC" to be drerecated definitions; "__ppc__" and "__PPC__" being valid.
