Hmm. The list from -ki package-depends
is not always specific to one specific
use. For example, on a development machine
where various flavors of binutils have
been built and installed. First I show
the list of various flavors installed:
# pkg info "*binutils*"
aarch64-binutils-2.33.1_2,1
aarch64-none-elf-binutils-2.33.1_2,1
amd64-binutils-2.33.1_2,1
binutils-2.33.1_2,1
powerpc-binutils-2.33.1_2,1
powerpc64-binutils-2.33.1_2,1
(If you do the above does one of the lines
of output have "native-" as a prefix?)
But here is what -ki package-depends
reports for lang/gcc9:
# cd /usr/ports/lang/gcc9/
# make -ki package-depends
gmp-6.2.0:math/gmp
indexinfo-0.3.1:print/indexinfo
mpfr-4.1.0:math/mpfr
mpc-1.1.0_2:math/mpc
aarch64-binutils-2.33.1_2,1:devel/binutils
aarch64-none-elf-binutils-2.33.1_2,1:devel/binutils
amd64-binutils-2.33.1_2,1:devel/binutils
binutils-2.33.1_2,1:devel/binutils
powerpc-binutils-2.33.1_2,1:devel/binutils
powerpc64-binutils-2.33.1_2,1:devel/binutils
Note that I do not get a one prefixed with
"native-" but I get every one of the installed
flavors of binutils is listed, not just one.
For reference, in my context:
# make -VPKGNAME
binutils-2.33.1_2,1
What happens if you try:
# pkg info native-binutils
? For reference, my context gets:
# pkg info native-binutils
pkg: No package(s) matching native-binutils
# pkg info binutils
binutils-2.33.1_2,1

Description :
The GNU Binutils are a collection of binary tools. The main ones are:
* ld - the GNU linker.
* as - the GNU assembler.
Most of these programs use BFD, the Binary File Descriptor library, to do
low-level manipulation. Many of them also use the opcodes library to assemble
and disassemble machine instructions.
This port may be used as a replacement for the system binutils and support
features from the latest versions of GCC.
For cross-compilation, see the devel/cross-binutils port.
