The /etc/rc.d/ldconfig ends up reading the contents of the files in
that directory to build the /var/run/ld-elf.so.hints file. It's a lot
more efficient for the few ports that put their libraries in
nonstandard locations to create /usr/local/libdata/ldconfig files
rather than have /etc/rc.d/ldconfig have to scan all the subdirectories
in /usr/local/lib. My system, for example, has 1500, wiuth the worst
offender being perl5. Most of those subdirectories don't need to be
listed in ldconfig since they are directly opened via the dlopen()
function and an absolute path.

Sounds like the databases/libdbi-drivers port needs to add a
USE_LDCONFIG= ${PREFIX}/lib/dbd
line to its port Makefile.
