Well, I decided to replace libpng-1.5.0beta34 with libpng-1.4.3 stable  
version and recompiled it. The interesting thing in Mplayer configure.log  
after that is:


============ Checking for PNG support ============

#include <png.h>
#include <string.h>
int main(void) {
   printf("png.h : %s\n", PNG_LIBPNG_VER_STRING);
   printf("libpng: %s\n", png_libpng_ver);
   return strcmp(PNG_LIBPNG_VER_STRING, png_libpng_ver);
}

Result is: yes

So, the warning still there, but the compilation process not stopping, but  
continuing. I don't know, is it ok when this message still there, although  
the make process continues?

Then next error appears:

ene/include/dirac   -I/home/Eugene/include/schroedinger-1.0  
-I/home/Eugene/inclu
de/orc-0.4   -c -o unrar_exec.o unrar_exec.c
unrar_exec.c:24:22: fatal error: sys/wait.h: No such file or directory
compilation terminated.
make: *** [unrar_exec.o] Error 1

I understand that error. It is because I have not got this package. But  
where can I find the package with that files (unrar_exec.o, unrar_exec.c)  
and what is it called?
Thanks for your attention.
