Actually its likely easier to use a run-time rather than a compile-time
setting. The parentdir/linto dependencies are implicit
in the sense that there's no Requires: that is explicitly needed.
The dependencies are synthesized from pre-existing information in
a package.
To configure parentdir/linkto dependencies at run-time:
1) Make sure that RPM_OPTIONAL_DIRNAME_AND_SYMLINK_DEPS is enabled.
That is likely already the case if you haven't disabled. Check
config.h after running ./configure (and you can always edit config.h
after running configure if all else fails).

2) Edit /etc/rpm/macros (create if not existent) to add
%_check_dirname_deps 0
%_check_symlink_deps 0
to disable.
3) Turn on symlink dependencies: its less annoying than parentdir deps and
is almost always a package failure when encountered (aka a dangling symlink
that points to a non-existent end-point).
4) When you have a mostly stable/unchanging set of packages installed, then
turn on parentdirectiory dependencies. Then do
mkdir -p /etc/rpm/sysinfo
rpm -Va --nofiles | grep '^/' | sort -u > /etc/rpm/sysinfo/Dirnames
(there is a --orphandirs option to rpm -Va that does the above, I'm just too
lazy to check
how to use it: its a popt alias that does essentially the above).
5) Run
rpm -Va --nofiles
periodically, and when you see a "orphan directory", i.e. a directory that
isn't explicitly in any package file manifest, then just add that directory
to /etc/rpm/sysinfo/Dirnames.
The annoyance is mostly that RHEL5/RHEL6 never bothered to do the QA to
ensure that rpm --erase would also remove created directories.
BTW, if you are going to use rpm-5.3.11` on RHEL5/RHEL6, then you need
to convert your rpmdb so that header instance numbers are always in
network order (needed for optimal btree access).
