mplayer is fine by itself. It's something lower down that mplayer uses 
during configuration/compiling.

I personally about a week after the pthread changes when several ports 
had been updated and fixed used the more radical method. I did a 
pkg_deinstall -a, then a rm -rf /usr/local, then reinstalled all ports I 
used from scratch letting them bring in their dependancies as and when 
required.

It took me the best part of a saturday afternoon but now at least I have 
a nice and tidy /usr/local. Have removed all the ports that I didn't use 
any longer or which were not required. And everything is compiled 
against libpthread properly and there is nothing at all using libc_r. I 
have confirmed this by using the sysutils/libchk port. libc_r is one of 
the ones that is unreferenced by anything now.

Since doing this I have absolutly no problems or issues with anything 
(including mplayer).

Matt.
