>Description:
mail/opendmarc fails to build with pkg-config not found:

...
checking whether to build static libraries... yes
checking pkg-config is at least version 0.9.0... no
configure: error: pkg-config not found
*** Error code 1

Stop.
make[1]: stopped in /usr/pkgsrc/mail/opendmarc
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/mail/opendmarc

Same behaviour on -current.  'which pkg-config' returns /usr/pkg/bin/pkg-config, 
and the version of that is 2.3.0.

./tools/bin/pkg-config is also there,  The .work.log indicates it's trying to run:

/usr/pkgsrc/mail/opendmarc/work.pepe/.tools/bin/pkg-config --atleast-pkgconfig-version 0.9.0
set args --atleast-pkgconfig-version 0.9.0; shift; PKG_CONFIG_LIBDIR=/usr/pkgsrc/mail/opendmarc/work.pepe/.buildlink/lib/pkgconfig:/usr/pkgsrc/mail/opendmarc/work.pepe/.buildlink/share/pkgconfig false  "$@"

and that has a return code of '1'.

Happy to provide additional debugging info if that would be useful.

>How-To-Repeat:
   cd /usr/pkgsrc/mail/opendmarc
   make install
>Fix:
   Please. Thanks.
