Did you read the "Porting" chapter in the glibc manual? Basically, to
port glibc to another platform you'll need to fill in the sysdeps
directory for that platform. You need to understand how the sysdeps
directory works. It's described in that chapter.

You'll also need to understand the internals of glibc and the
interface glibc uses on your platform (the system call interface of
the FreeBSD kernel in your case). I would say that the best thing to
do is to start with testing the code already in the unofficial
port. Then try to fix any problems you'll encounter and you will
probably learn the things you need to know on the way.

I CC'd the address@hidden mailing list, they might be
able to tell you more about it.
