Summary: python-2.4.4 on freebsd-6: _curses extension doesn't build

Initial Comment:
'uname -rms'
FreeBSD 6.2-STABLE i386

trying to build python-2.4.4 from ports/lang/python24, i get the
following messages, where earlier versions have been compiled and
installed w/o problems:

the 'readline' extension builds fine, though:

I also tried this command after noticing that freebsd needs some special
define for wchars:

$ make 'CFLAGS=-O -D__wchar_t=wchar_t' 'WITH_THREADS=YES' 'WITHOUT_IPV6=YES'
