[Libguestfs] installing supermin on debian10

Hello I am trying to install supermin on debian 10 (buster) and I am getting the following error: checking /usr/sbin/mke2fs -t or -T... -t checking for EXT2FS... no configure: error: in `/root/supermin-5.1.16': configure: error: The pkg-config script could not be found or is too old. Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config. Alternatively, you may set the environment variables EXT2FS_CFLAGS and EXT2FS_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. To get pkg-config, see <http://pkg-config.freedesktop.org/>;. See `config.log' for more details Note that I have installed all the required dependency packages which I could find in the README. Can anyone help making this work? Regards, Peter
