trafshow and libslang

[Luigi Rizzo]

hi,
there seems to be no way to build trafshow without slang -- even
if the port's Makefile tries to remove slang from LIB_DEPENDS if
you set WITHOUT_TRAFSHOW_SLANG, config will detect the library and
use it anyways.

Does anyone have ideas on how to convince config to stick to ncurses
instead (i am not fond of slang, and anyways it's an additional
library that i do not need to carry in picobsd configs)

	cheers
