>Environment:
FreeBSD coot.ravenbrook.com 5.3-RELEASE FreeBSD 5.3-RELEASE #0: Fri Nov  5 04:19:18 UTC 2004     root at harlow.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386
>Description:
On a clean FreeBSD 5.3 machine, do:

cd /usr/local/lang/python
make install

and you will see, amongst other things:

checking ncurses.h usability... no
checking ncurses.h presence... yes
configure: WARNING: ncurses.h: present but cannot be compiled
configure: WARNING: ncurses.h: check for missing prerequisite 
headers?
configure: WARNING: ncurses.h: proceeding with the 
preprocessor's result

The Python guys looked at this and found a problem with the FreeBSD headers.  See https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1160534&group_id=5470 for full background.
>How-To-Repeat:
Build /usr/ports/lang/python on a clean install and look carefully at the autoconf output.
