There are a lot of ports that are linked to the devel/ncurses port and 
they don't register devel/ncurses as dependency.

checking for gmsgfmt... /usr/local/bin/msgfmt
/libexec/ld-elf.so.1: Shared object "libncurses.so.5.7" not found, 
required by "xgettext"
/libexec/ld-elf.so.1: Shared object "libncurses.so.5.7" not found, 
required by "msgmerge"
/libexec/ld-elf.so.1: Shared object "libncurses.so.5.7" not found, 
required by "msgfmt"
configure: error: GNU gettext tools not found; required for intltool

(A script failed because of the new ncurses update) and :

markand at Melon /usr/ports/editors/leafpad $ pkg_info -R ncurses-5.8
Information for ncurses-5.8:

Required by:
rxvt-unicode-9.10_1

So there is obviously a problem. I think the problem is : a port that 
need ncurses and does not set a RUN_DEPENDS or devel/ncurses will 
attempt to link to the base ncurses or if devel/ncurses is installed it 
will linked to this version but will *NOT* register this depend.

I think we need to add something like USE_NCURSES in the bsd.port.mk 
infrastructure, then the port will look itself if ncurses is available 
in the base system or will add a RUN_DEPENDS that registers the 
dependency of devel/ncurses port.

As you can see:

markand at Melon ~ $ ldd `which qemu`
/usr/local/bin/qemu:
	libm.so.5 => /lib/libm.so.5 (0x80080b000)
	libthr.so.3 => /lib/libthr.so.3 (0x80092b000)
	libz.so.5 => /lib/libz.so.5 (0x800a44000)
	libgnutls.so.40 => /usr/local/lib/libgnutls.so.40 (0x800b59000)
	libpcap.so.7 => /lib/libpcap.so.7 (0x800d01000)
	libutil.so.8 => /lib/libutil.so.8 (0x800e32000)
	libSDL-1.2.so.11 => /usr/local/lib/libSDL-1.2.so.11 (0x800f42000)
	libX11.so.6 => /usr/local/lib/libX11.so.6 (0x8010aa000)
	libncurses.so.5.8 => /usr/local/lib/libncurses.so.5.8 (0x8012df000)
[... snip ...]

And :

markand at Melon ~ $ pkg_info -r qemu-0.11.1_6 | grep ncurses
markand at Melon ~ $

If you deinstall ncurses, qemu will link to the base system.
