In fact, it can be build on alpha if it is linked against libio.
But I'm not sure whether it works or not on alpha.
Feel free to fix and test these ports on alpha.
I have left out zircon, which seems to have provisions for tcl81, and
hfsutils and filerunner, which have been upgraded and probably checked
in the meantime.
but aren't in a tk virtual category from
awk -F\| '$9 ~ /tk-/ && $7 !~ /tk/ {print $1}' INDEX
I didn't do anything about the ports which depend on things which depend
on a tk revision. I'd be afraid that the depended-upon port might change
and thus outdate the virtual category in the depender.
