maybe my problem is another,
but I still have a hang

# emerge -v -1 sys-libs/ncurses

These are the packages that would be merged, in order:

Calculating dependencies ... done!
[ebuild     U ] sys-libs/ncurses-5.7-r2 [5.6-r2] USE="cxx%* gpm unicode -ada% -debug -doc -minimal -profile -trace (-nocxx%)" 0 kB
...
** Building terminfo database, please wait...
Running tic to install /var/tmp/portage/sys-libs/ncurses-5.7-r2/image//usr/share/terminfo ...

	You may see messages regarding extended capabilities, e.g., AX.
	These are extended terminal capabilities which are compiled
	using
		tic -x
	If you have ncurses 4.2 applications, you should read the INSTALL
	document, and install the terminfo without the -x option.

here it hangs
I waited about hour,
it eats processor time and no output even in strace

# strace -p 24731
Process 24731 attached - interrupt to quit
^CProcess 24731 detached
