If you build OpenLDAP with only shared libraries (--disable-static), and try to
build the ldbm backend with gdbm, it fails.

LDFLAGS="-L/path/to/lib" CPPFLAGS="-I/path/to/include" ./configure \
  --enable-shared --disable-static --disable-bdb --enable-ldbm
--with-ldbm-api=gdbm \
  && make depend && make

(where /path/to/lib and /path/to/include are where gdbm libraries/headers are
installed)

Results in:
