Problem installing Python 2.4.3 on FreeBSD 5.3-RELEASE-p31

[james at uh-hosting.co.uk]

I have a problem installing Pyhton 2.4.3, running "./configure
--with-threads=no" completes, but gives the warning:

configure: WARNING: curses.h: present but cannot be compiled
configure: WARNING: curses.h:     check for missing prerequisite
headers?
configure: WARNING: curses.h: see the Autoconf documentation
configure: WARNING: curses.h:     section "Present But Cannot Be
Compiled"
configure: WARNING: curses.h: proceeding with the preprocessor's result
configure: WARNING: curses.h: in the future, the compiler will take
precedence

Running "make" then gives the error:

gcc -shared build/temp.freebsd-5.3-RELEASE-p31-i386-2.4/_cursesmodule.o
-L/usr/local/lib -lncursesw -o
build/lib.freebsd-5.3-RELEASE-p31-i386-2.4/_curses.so
Segmentation fault (core dumped)
*** Error code 139

I assume this is related to the configure warning... ?  Same error with
just a standard "./configure" and "make".

Any help would be great :)
