I don't know why spl builds on clang but fails on gcc due to a flex precedence issue. Rather, I don't know why the flex issue doesn't affect clang. There was a patch provided by a fork nearly four years ago that fixes the gcc build nicely. The bitbucket issue warns that more eyes should review the fix though.
