There should be a requirement to check if a port exists before committing something right into the master

[Sergio Had]

Otherwise we get this: 
https://github.com/macports/macports-ports/commit/6e2c1e19a4ffce5d59a9cdf8147022ad176dffed

While LimeChat has existed for 4 years in MacPorts: 
https://github.com/macports/macports-ports/commits/8c30b0e9fd88d94c115b38c92809b909c4eac9aa/aqua/LimeChat/Portfile

And now two conflicting ports for the same thing.
