Ok, got under the truck over the weekend to take a look - not the clutch line. The piece of the slave cylinder that the pin goes through was cracked and let the clutch line pop right out. Looking at it, I'm convinced that the seller buggered it up when he replaced the line. Another good reason on why I do my own work...
So placed the order for the parts through RockAuto and hope they will be here this week. Why the fook they made the slave out of plastic is a whole 'nuther matter... Say what you will about foreign vehicles, but at least my Toyota has a metal master and slave and a metal line that threads into each end...
