openldap @2.4.40: Undefined symbols: _posix_memalign

Description
The build fails with the error
:info:build Undefined symbols: :info:build "_posix_memalign", referenced from: :info:build _mdb_env_copyfd2 in libbackends.a(mdbmdb.o) :info:build ld: symbol(s) not found :info:build collect2: ld returned 1 exit status :info:build make[2]: *** [slapd] Error 1
I added the following line to openldap's Portfile was able to upgrade:
config.args-append --disable-mdb
Of course, I only half know what I'm doing. I am attaching the log for the failed upgrade.
I found a clue here: http://code.metager.de/source/history/openldap/libraries/liblmdb/ under Revision 4008e5e58337feb8a5ab29b7f939b1831d3f6d75.

The same failure happens on PPC Tiger, Mac OS X 10.4.11.

| Summary: | openldap @2.4.40+overlays build fails on ppc G5, OS X 10.5.8 during upgrade → openldap @2.4.40: Undefined symbols: _posix_memalign |
Same on Tiger i386 without the overlays variant.
You were able to build by disabling mdb... What is mdb and what is the significance of disabling it?

From what I've gathered, mdb (shorthand for "Lightning Memory-Mapped Database) will soon be the favored backend to openLDAP, as it is openldap's own in-house database. Currently the primary backend is hdb (hierarchical database), which has superseded bdb (Berkeley database), though it still uses bdb for data storage (hdb improves performance through additional caching and indexing). Openldap's default configuration builds both hdb and bdb--and now mdb. I do not know if the previous version of openldap (2.4.39) was configured to build mdb by default and some change in mdb's code is the source of the build failure, or whether openldap 2.4.40 is the first version to enable mdb. I'll download the old version and check out its configure file, then let you know.

openLDAP @2.4.39 does default-enable mdb, so I suppose they've changed some code.
comment:8 Changed 10 years ago by zzanderr
Apparently, the developers at openLDAP were going to use memalign rather than posix_memalign because of its ubiquity. Then they discovered that OS X only has posix_memalign and only in the more recent, fully POSIX-compliant versions. They mentioned using valloc for older versions of OS X, but do not seem to have followed through with it in openLDAP @2.4.40.
