Odd clBuildProgram function error

Last thing that I can probably think of is how you compile it. There was an instance that I encountered where two identical .aocx and host program were compiled, but one found the altera platform and the other didn't, but the only difference between the two was how it was compiled. There was a flag set on one of them that I'm guessing made the compiler use a different set of libraries. Changing the make file to the same fixed the issue. Not the same as the error you're encountering, but maybe the fix is similar.
