If I were doing this then I'd take my C library and write some kind of 
wrapper for it using Parrot. Parrot's NCI (Native Call Interface) lets you 
load a dynamically linked library/shared object and call functions in it (I 
once wrote a script that auto-gen'd Parrot calls for the entire Win32 API). 
Then you can write a Perl6 module that inlines PIR (Parrot code) that loads 
your Parrot code wrapping the C library and calls the functions you want, 
and wrap all of this again in some nice Perl 6 module/class.

I believe that the plan is that Pugs will be re-written from Haskell into 
Perl 6, so writing your binding to the C library with Haskell's support for 
doing so probably won't be a long-term solution to your needs.

Hope this helps, and corrections welcome (all(qw/beer wine baileys/) == 
none(@good_idea) ;-)).
