I forgot to say that make target is `package-recursive'. I
tried to get PKGNAME with package-depends:
root@jdtpkxb:/usr/ports/lang/gcc9 # make -ki package-depends
gmp-6.2.0:math/gmp
indexinfo-0.3.1:print/indexinfo
mpfr-4.0.2:math/mpfr
mpc-1.1.0_2:math/mpc
native-binutils-2.33.1_2,1:devel/binutils
root@jdtpkxb:/usr/ports/lang/gcc9 #
But PKGNAME in devel/binutils is:
root@jdtpkxb:/usr/ports/devel/binutils # make -VPKGNAME
binutils-2.33.1_2,1
root@jdtpkxb:/usr/ports/devel/binutils #
I don't know why it is. As far as I see
devel/binutils/Makefile, FLAVOR default is `native' and
PKGNAMEPREFIX should be null.
What happens ?
