After I patched the existing libltdl, it's fine. Before, it wasn't.

install libbar into /opt/lib/
ensure /opt/lib isn't in ldconfig, or LD_LIBRARY_PATH
build FreeRADIUS with LDFLAGS=-L/opt/lib
install rlm_foo into /usr/local/lib/
rlm_foo -> libbar
ensure radiusd.conf, libdir = /usr/local/lib
ldd rlm_foo should return error
running freeradius should link rlm_foo, fail to link libbar,
and return a partial ltdl_handle*.
It's pretty easy to reproduce if you put libraries into a place
where your dynamic linker can't find them.
