I know virtually nothing about perl6, but it would seem that the error is in 
relation to:

use lib './lib/Math/.';

(Providing args such as './lib/Math/.' to a "use" directive is apparently 
not yet supported.)

So the error really has nothing to do with Inline itself.

I was told a few years ago that perl6 doesn't have XS. That being so, I 
don't see how Inline::C (in its current form) could ever work with perl6 - 
because, under the hood, Inline::C does little more than write (and compile) 
an XS file.
