childapp.py's subprocess.popen can't open dynamically linked binaries under openbsd 4.6/python 2.5.4

Good Afternoon,

I'm trying to port freevo svn install to openbsd 4.6 and I think I'm  
nearly there and ready to capture and blog the changes I had to make :)

However I face hopefully one last issue:

childapp.py uses the python subprocess popen call which executes  
mplayer gives a quick screen blank or redraw and the OS tries to load  
mplayer I see if I watch 'ps ax' while trying to watch a movie.  But  
nothing actually plays and the mplayer-stderr* log file reads:

/usr/local/bin/mplayer: can't load library ''

I see if I make /usr/lib/mplayer a simple /bin/sh script I can run any  
statically compiled binary in here from freevo with no errors.

However if place a dynamically compiled binary in my script to be  
called it fails and logs to the mplayer-stderr*:

$BINARY_PATH/$BINARY: Can't load library ''

Currently my shell script looks like this:

#!/bin/sh
export LD_LIBRARY_PATH=/usr/lib:/usr/libexec:/usr/X11R6/lib:/usr/local/lib
/usr/bin/ldd /usr/local/bin/mplayer.real >/tmp/output

This results in log lines of the following:

/usr/bin/ldd: can't load library ''

I think this is probably OpenBSD specific but on my googles can't find  
a way to allow python to call dynamically linked binaries and be able  
to find/load the libraries it needs :(

Anyone know a way around this or a good place to start digging?

Alistar =)
