Yes, it's actually no good idea to permanently add the compat libdirs
to your LD_LIBRARY_PATH, you must not try to mix linux and BSD
libraries, unless you write a wrapper for these situation like the
flashplugin in FreeBSD mozilla.

Hmm...ldconfig is just evil. If you add the linux compatibility libs to
the ldconfig path for your BSD build environment, you would again break
binary consistency.
I suppose symlinks don't hurt too bad if done correctly, but personally
I don't like it here.

I'd suggest the following: If adding /usr/compat/linux/lib to
LD_LIBRARY_PATH solves the problem for you but you don't want to define
it for your entire environment, why not just put in something like

alias mplayer env LD_LIBRARY_PATH=/usr/compat/linux/lib mplayer

in your shell startup file?
