FreeBSD Port: mplayer-0.90.0.110_2 and RealAudio doesn't find linux libm

[Stephen Casner]

I have installed the subject mplayer port and the linux-realplayer port 
on FreeBSD 4.8-RELEASE.  Trying to decode a .rm file using the RealAudio 
encoding results in the error message:

Error: Shared object "libm.so.6" not found

That file is present in /usr/compat/linux/lib/libm.so.6, but that 
directory is apparently not in the search path.  Adding that directory 
to LD_LIBRARY_PATH solves the problem, but it seems that might cause 
some the linux library to be selected by non-linux programs.

I tried building mplayer with that directory added to the 
--with-extralibdir configure argument, but that didn't help (I presume 
because it's not the mplayer binary that needs to load libm, but rather 
the sipr.so.6 codec library that needs it, and I'm not sure how mplayer 
loads codecs that are linux libraries).

This question was asked on the mplayer-users list where the answer 
suggested installing symlinks to the desired files, or to run ldconfig. 
  What is the correct approach?
