When I attempted to run checklink on the command line like this:
I got the following error message:
"-T" is on the #! line, it must also be used on the command line.
To get this to work, I had to run the command as follows:
C:\Users\chris\>perl -T C:\perl64\site\bin\checklink http://osric.com
The -T switch is to enable taint mode, which helps protect the program from malicious input.
