I'm getting the same error here - it seems like test program missed a 
reference to "pow" (needs -lm).

what I did was in m4/ax_check_graphics.m4
where it says:
  AC_CHECK_LIB([png],[png_get_io_ptr],passed=`expr $passed + 
1`,failed=`expr $failed + 1`,[-lz])
I changed it to:
  AC_CHECK_LIB(png,png_get_io_ptr,passed=`expr $passed + 1`,failed=`expr 
$failed + 1`,[-lz -lm])
I removed the square brackets because I think there not needed here.

and it works here. does it solve it for you?

please report it to bug tracker (with solution)
