I recently installed NAGWare's Fortran 95 compiler, 
and it installed its shared libraries into
/usr/local/lib/NAGWare.  To get the compiler to work,
I of course needed to use "ldconfig -m".  When I rebooted
the system, I found that the ldconfig portion of /etc/rc
does not recurse into subdirectories of /usr/local/lib
(which is probably a Good Thing), so I had to manually
run "ldconfig -m" to add /usr/local/lib/NAGWare.

There appear to be several options:

 (1) Upon booting run "ldconfig -m".  This could be done
     either manually by root or perhaps from rc.local.

 (2) Move the NAGWare shared libraries up one directory
     into /usr/local/lib.  This is simple, but would make
     updating third party software more difficult because
     of possible stale libraries.

 (3) Edit /etc/rc to explicitly include /usr/local/lib/NAGWare
     This becomes an annoyance when running mergemaster.
     It also isn't a general solution for other third party
     software installations.

 (4) Tell all users on the system to add the directory to 
     a LD_LIBRARY_PATH variable.

 (5) Add another knob to rc.conf.  A possible solution to
     the third party software problem introduces the
     extra_ldconfig_paths to /etc/rc.conf and apply this
     diff to /etc/rc
