Hi Guix team,
I am struggling on this error but can not get it resolved.
Please kindly help.

```
What I have invetigated/tried:
Error is due to failure in verify-config(kconfig.scm).
I understand that this is because can not find correspoding config in `.config`.
So I try to do a manual kernel config via
```
guix system reconfig system.scm -K
cd /tmp/guix-build-linux-libre-bpf-6.8.8.drv-0/top
source environment-variables
cd linux-6.8.8
make menuconfig
```
But `make menuconfig` raise error:
```
*
* Unable to find the ncurses package.
* Install ncurses (ncurses-devel or libncurses-dev
* depending on your distribution).
*
* You may also need to install pkg-config to find the
* ncurses installed in a non-default location.
*
make[2]: *** [scripts/kconfig/Makefile:232: scripts/kconfig/mconf-libs] Error 1
make[1]: ***

make: *** [Makefile:240: __sub-make] Error 2
```
Then I installed ncurses, pkg-config. But still same error.
