x11/xorg port can not be build
i want to install x11/xorg but it gives error,
I also get same error when i wanted to install python port.
make: "/usr/dports/Mk/Uses/python.mk" line 486: Cannot open /usr/dports/lang/python38/Makefile.version
make: Fatal errors encountered -- cannot continue
make: stopped in /usr/dports/devel/llvm80
*** Error code 1
it seems that you have an issue with lang/python38 rather than xorg port itself.
Concerning Xorg, is there anything specific that requires you to build it ? You can install it in a simple way using the pre-built binary packages provided by several mirrors as stated https://www.dragonflybsd.org/docs/handbook/X/.
For example running "pkg install xorg" is enough to install it.
