Hi Jim,
Thanks for resolving this issue. The DL_LIBRARY variable was introduced in was:
>From Alberto Luaces, "he new GNU linker, "gold", is going to replace
soon the current ld in
almost all Linux distributions. Although it is 100% compatible with ld,
by default it gives an error if a library has unresolved symbols at link
time, that is, it has set -Wl,--no-undefined by default. Debian folks
have found that libosg.so and libosgDB.so use some functions belonging
to libdl.so {dlsym,dlopen,dlclose,dlerror} without linking to it.
My changes link those two libraries to libdl.so explicitly in the same
way it is already done for libm.so and librt.so."

I've now merged your workaround for when DL_LIBRARY isn't found.
Given that FreeBSD used GNU linker as well there is good chance that
it too will eventually need the inclusion of DL_LIBRARY, you change is
compatible with this possibility.
Robert.
