I can reproduce this with both i386/amd64 6.2-RELEASE with devel/ncurses
installed. ldd ${WRKSRC}/build/.../_curses.so says it is linked against
local/lib/libncurses.so.6 (ktrace on python executable also confirms that).
gdb shows (I have devel/ncurses-devel installed instead of ncurses 5.6):

I can build python 2.4.4 without problems on 7.x i386, which has ncurses
5.6 in base. Moreover, python 2.5 builds fine on these machines, i.e.,=20
with devel/ncurses installed.=20
So, my guess is that devel/ncurses + base ncurses confuses python 2.4.4
build in someway...
