How to compile lib/libisc ? (Work in progress: updating to BIND 9.3.2)

[Petr Janda]

Everytime I try to compile this library from it's directory I get this 
error:

Assembler messages:
FATAL: can't create isc/nls/msgcat.o: No such file or directory
/usr/head_src/src/lib/libisc/../../contrib/bind-9.2.4rc7/lib/isc/nls/msgcat.c:130: 
fatal error: error closing -: Broken pipe
compilation terminated.
*** Error code 1

Stop in /usr/head_src/src/lib/libisc.

Im in middle of updating BIND to 9.3.2 in the base but get this error in 
entropy.c during buildworld

IBAGE=0  -c

error: `PORT_NONBLOCK' undeclared (first use in this function)

Im just trying to figure out what Im missing/whats wrong with my updated 
lib/libisc/Makefile without having to do buildworld everytime i make a 
change.

Cheers
