That could be any of a large number of problems (mostly configuration
problems rather than code...). That's running a script that looks around
for shared libraries and uses those:
https://github.com/torvalds/linux/blob/master/scripts/kconfig/lxdialog/check-lxdialog.sh
along with the rules in
https://github.com/torvalds/linux/blob/master/scripts/kconfig/Makefile
In particular, note that the shell script only uses pkg-config to decide
if the libraries _exist_, but ignores its advice on _where_ to find the
libraries.
If I had to debug this problem, I'd setup a debug-version of ncurses
and get the script to run _those_ libraries, and (for instance) modify
the Makefile to use valgrind to log problems when running mconf.
With some work (and perhaps turning on the traces),
you'll see what's happening.
