no 'nameser.h' on OSX install?

hi all,

i'm building bind930 on osx 10.3.7

i note that the bind930 source tree includes

./lib/bind/include/arpa:
inet.h
nameser.h
nameser_compat.h

these files, iiuc, are needed on OSX for use by its BIND_8_COMPAT directive.

yet, when building --with-libbind, although libbind builds as expected, i find
no trace of the actual nameser.h in the _install_ dirs.

have i missed a build switch somewhere? or, should i simply copy the
aforementioned to my install-path include dirs?

thx,

richard
