Trouble Installing Mplayer

[EmmGunn]

Hi All!
I'm having trouble installing mplayer.  The specific problem seems to  
be with the perl5.8 port.  I get the following error when it tries to  
install:

--->  Building perl5.8
Error: Target org.macports.build returned: shell command " cd "/opt/

I'm not sure what math.h has to do with perl.  It's a GPAC file.  I  
think it was installed with mp4box.  Was something overwritten?  I  
tried to do some googling but didn't have any luck.  Part of the  
problem is that I'm not a UNIX pro so what I did find was greek to  
me.  Any dummying down that you can manage in your response would be  
very much appreciated.  Thanks for any hints.
