8.2 Admin Pack broken?

I'm trying to compile in the "adminpack" into PostgreSQL 8.2.3, but it
doesn't want to build.

According to the instructions, I change into "contrib/adminpack" and run
"make" followed by "make install."

However, make fails:

This is on FreeBSD 6.1, I've built and installed PostgreSQL 8.2.3
(running nicely) - I have Bison and M4 installed - is there anything
else I need?
The "nls-global.mk" and "nls.mk" files don't exist.

Any help would be appreciated!

Thanks,

Andy.
