shepherd: PKG_PROG_PKG_CONFIG is m4_require'd but not m4_defun'd

[Attila Lendvai]

i've pulled and reconfigured into the recently merged core-updates changes, and 
then i tried to compile shepherd from a git checkout of the devel branch.


$ ./configure
[...]
./configure: line 7268: PKG_PROG_PKG_CONFIG: command not found
configure: error: pkg-config is missing, please install it
$ pkg-config --version
0.29.2


then i tried to autoconf it:


$ autoconf
configure.ac:52: warning: PKG_PROG_PKG_CONFIG is m4_require'd but not m4_defun'd
aclocal.m4:49: GUILE_PKG is expanded from...
configure.ac:52: the top level

the referenced line is this: GUILE_PKG([3.0])

i.e. guile seems to be involved somehow.

any ideas?

“The very possibility of conflict over a resource renders it scarce, giving 
rise to the need for ethical rules to govern its use. Thus, the fundamental 
social and ethical function of property rights is to prevent interpersonal 
conflict over scarce resources.”
