Searching for the Correct License

mchappee asks: "I'm about to release an Open Source software package for Linux. I'd like to have the code covered under the GPL, but I cannot because it links to commercial libraries. There are lots of Open Source licenses out there, but time and again I see people and companies being attacked for choosing the wrong one. So I ask you, the nerds, to enlighten me. What license will protect my code and ensure that it will always remain Open Source, yet will allow me to link to commercial libraries? "
