Hi,
After my yesterday’s upload of pkgconf replacing pkg-config, Helmut was
fighting a dependency cycle in rebootstrap:

Having looked at libxcrypt’s configure.ac, I found that it only uses
pkg-config’s m4 script in one place, and ships a replacement compat
macro to use when it’s not present. Indeed, building libxcrypt without
pkg-config doesn’t result in a failure, and everything seems in order
except an error message:
...
checking whether the compiler supports GNU C... yes
checking whether gcc accepts -g... yes
checking for gcc option to enable C11 features... none needed
checking whether gcc understands -c and -o together... yes
checking whether make supports the include directive... yes (GNU style)
checking dependency style of gcc... none

../configure: line 4700: --atleast-pkgconfig-version: command not found
checking how to run the C preprocessor... gcc -E
checking whether make sets $(MAKE)... (cached) yes
The -dev binary package ships pkg-config files in the right place:
