Two equally frequent values

Write a program to find the first line of the input where two different
values appear the same number of times.

Input

The input comes in standard input stdin and consists of zero or more
integers separated by blank spaces and organized into zero or more
nonempty lines.

Output

The output must have the form "Line: ’...’ has some equally frequent
values" where the dots must be replaced by the first line in the input
in which there are two or more different values that appear with the
same nonzero frequency; or, if no such line exists in the input, the
message "No line has equally frequent values". Make sure that the output
format matches the examples.
