When compiling, I get "No DATAMODEL_NATIVE specified"?

There are two typical causes for this; one is compiling with
a bad install of gcc (See 5.9). The other possible cause
is installing BIND 4.x or 8.x header files, e.g., by running
"make install". You can check this with "pkgchk SUNWhea"; if
this returns any errors, you need to recover the damaged include
file from the original installation media.
