If the OP will supply the data, I pretty much guarentee that this can be solved directly in Perl more quickly that you can load the data into MySql and add a "geospatial index", let alone construct & run the query, and then retrieve the results.

And with less lines of code.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
