Hi,

you are right, your defconfig works because BR2_PACKAGE_NCURSES_WCHAR is 
disabled. All autobuilder failures occur with BR2_PACKAGE_NCURSES_WCHAR=y.

sngrep.mk contains --disable-unicode due to problems while detecting 
ncurses.h, see commit log for details:
https://git.buildroot.net/buildroot/commit/package/sngrep?
id=bf09290977a5b43f53479dd52777fde0bb20bf5a

Using --disable-unicode forces the configure script to check for the 
ncurses libs without "w" in their name only:
https://github.com/irontec/sngrep/blob/master/configure.ac#L77, but they 
are not present with BR2_PACKAGE_NCURSES_WCHAR=y leading to the configure 
error seen by the autobuilders.

Quick fix: depends on !BR2_PACKAGE_NCURSES_WCHAR

Regards, Bernd
