723 failed to compile [FreeBSD-4.7-STABLE]

I have 722 installed and tried to build 723.
723 fails to compile. Attached to this message is the output
of the build as captured by script(1).

I already sent a PR to freebsd-ports but the answer was that
this already happened and people got to compile it without
changing anything (that they knew of, I guess).
I am getting this error with FreeBSD-4.6.2p2 through 4.7RC0
and now 4.7-STABLE (updated last night)

Someone mentioned that this error is related to the lack of
awk in the system. I have:
awk: /usr/bin/awk
nawk: /usr/bin/nawk
and just in case I added a link in /usr/local/bin (it's in
the PATH): gawk -> /usr/bin/awk
[fernan(at)pi] awk --version
GNU Awk 3.0.6

I am now turning to postgres people for help. I am writing
pgsql-ports as said on the pgsql mailing lists page.

Thanks in advance for any tip or suggestion,
