So, I was looking for XILINX CPLD components when I found this
Here I happen to have v6.6 installed on my MacOSX laptop.
But if I try to open the library I get the following error message:
Eagle for Mac OS X can't update file
(data structure is older than version 4.11)
I have also tried EagleCAD v5.12, but it's still a no go
