Looking at the error report, I'd start with the easier ones
like the "undefined" that would seem to reflect missing headers
or perhaps mangled references, but just start with solving
things like "SIOCGPGRP". Given the way a kazillion compilers
work on n number of boxes , getting rid of the obvious might
make the question easier to answer.
