That's a strange line in there... almost like the OP stole it right out of another tutorial without crediting the author.

This is where the line that is causing problems came from:

following that tutorial from the beginning causes no issues.  All compiles as expected, though it's CentOS not Ubuntu.  The reason I used CentOS is that I was not able to run multiple gpu's under any other flavors of linux.
