Yes, it recommended to use the svn version.

`apt-get build-dep' did not help: the error was still there.  The solution was
suggested by Juan Jose Padilla: after the `./configure' step, in the file
mplayer/config.h, at line 483, after the line `#define HAVE_VIRTUALALLOC 0' , I
added the line `#define HAVE_MMAP 1', then ran `make' and `make install'.  It
must be a bug.  I suppose it would be all right to add that line anywhere else
in the file.

Thanks to all who replied
