In attempting to bootstrap my OS X.3 (Panther) Mac, I'm getting this 
error when it attempts to build tnftp:
ftp.c: In function `empty':
ftp.c:557: warning: variable `pfd' is implicitly extern
ftp.c:560: invalid use of undefined type `struct pollfd'
ftp.c:561: invalid use of undefined type `struct pollfd'
ftp.c:561: `POLLIN' undeclared (first use in this function)
ftp.c:561: (Each undeclared identifier is reported only once
ftp.c:561: for each function it appears in.)
ftp.c:565: invalid use of undefined type `struct pollfd'
ftp.c:566: invalid use of undefined type `struct pollfd'
ftp.c:575: invalid use of undefined type `struct pollfd'
ftp.c:577: invalid use of undefined type `struct pollfd'
My C knowledge is really limited so I don't know what this means so 
that I can even begin to attempt to fix this.  What do I do with this 
to bootstrap my Mac back to pkgsrc capability?
