[Automatic answer: RTFM (read DOCS, FAQ), also read DOCS/bugreports.html]
As I was trying to install  mplayer, I ran into the following minor
bug.  In compiling on my Debian 2.2.18 system using gtk this error
occured:

Looking at the configure.log file, I found:

ldd: can't open /tmp/mplayer-conf-1337261554-2694.o (No such file or
directory)

Result is: yes (using Xdpms 3)

-----------------------
>>From this, I gathered I should add the -lXdpms flag and it  subsequently
compiled ok.  Let me know if you need other info to address this.  I
used the download tarball 0.60 because I haven't got CVS to work yet
(I'm a newbie), so it might be fixed already.
