no, it says that Sage's readline will be built, because according to the test,
there is no ncurses (or tinfo) installed.

So I am puzzled that you say that the machine has libreadline-dev installed.
Could you post the contents of this package?
As well, I'd like to look at the output of

$ ldd `find /usr -name libreadline.so`

- which should look more or less like:

linux-vdso.so.1 (0x00007ffc2a2ce000)
libtinfo.so.6 => /lib/x86_64-linux-gnu/libtinfo.so.6 (0x000079942a162000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x0000799429fa1000)
/lib64/ld-linux-x86-64.so.2 (0x000079942a3f3000)

I gather that the test we have for system's ncurses is too
restrictive, and doesn't work
even though it should... (So this is a potential Sage bug)

To continue with this problem:
Indeed, readline gets built by Sage, but it's a bit broken, as I
gather it's not linked
against libtinfo:

To check this, please post the output of

ldd /usr/local/sage/sage-8.9/local/lib/libreadline.so.6

I don't know why this doesn't work, it might be something went wrong in

    get termcap library name from the readline's configure
--------------------

(so this might be another Sage bug)

----------------------------------------------------
Fixing at least one of these bugs might cure the systems you have, but
more info is needed...
What OS is that, precisely?

Sorry for trouble,
Dima


And Python2 does not do a very good job gathering what extra libs are needed,
 as its confugure output says

checking how to link readline libs... -lreadline -ltermcap

but then the error happens in the linking where one does not see -ltermcap, but
rather -lcursesw

(so this might be a Python2 bug)
