Gaddafi has a long track record of promoting radical Islam outside of his borders.
OK, assuming that your link is an unbiased one, let us then ask why Gaddafi is supporting radical islam.
Is it because he dreams of an AQ caliphate, encompassing all of the middle east, including his own country?
Does he dream of handing off power in Libya to an ayatollah (instead of to one of his sons)?
I'd argue that the answer to these two questions is obviously no. Then why does Gaddafi give any support to radical islam? To do below-the-public-radar damage to the West.
So, sure, Gaddafi is no friend, just as Saddam Hussein was no friend. But IMHO they are much less dangerous than the alternative, a string of radical islamic states.
And no, I do not buy the Bush 2 argument that the alternative to Arab dictatorship is Western-style democracy. Ain't gonna happen.
