Yes, you have said that in the previous mail. I wonder
_why_ you need
to
set it and if our documentation is not accurate. Have
you really set
PKG_CONFIG? Does it mean that you do not have pkg-config available in
your PATH?
my pkg-config is under /usr/lib/pkgconfig (gentoo). but libosmocore and
others are installed under /usr/local/lib/pkgconfig.
