It all depends.

One key area where libraries need at least some "native" language code is
wherever you need to interface with the underlying OS.

For more generic library code, the usual desire is to write it in the
source language as soon as possible.

Indeed.  

For example, Sun's original AWT (GUI windowing) implementation for Unix
relied upon X11 with the Motif library.  The new XAWT implementation has a
small core written directly to Xt and the rest is all done in Java.  The
result is a huge reduction in bugs and a nice increase in performance.

Have fun,
