seems to be a tonne of opportunity to smoke fink

i just wanted to follow up on this a little.

i noticed that *macports-libcxx* is the ‘good one’ and libcxx is the ‘old one’.

macports-libcxx+universal takes quite a while to install since it builds llvm-11 from scratch, but i suspect it’s worth it.

i think a discussion needs to happen to rename ken’s port to libcxx, and the latter to something that conveys since macports users should be pointed to his port before the existing one.

i really think macports-libcxx should replace libcxx. i noticed ken has added himself to the open tickets on libcxx and also christopher chavez has asked questions about its usefulness.

put briefly: i found libcxx to be unhelpful when (successfully) building nodejs14/18, opting to link in llvm’s libcxx from /opt/libexec

flat out, libcxx is ’too old’ to deserve retention of the primary name for a crucial library on macports. 
	-i noticed that ken removed himself from maintaining libcxx since it’s for snow leopard and older. 
		https://github.com/macports/macports-ports/commit/8ce65b33a1970046bdcb22ee86227301427d6135

i therefore think this should be on “the council”’s next meeting minutes.
	-thanks for all your hard work btw ken. i have to buy a beater sata ssd to start testing portfile edits with your macports-libcxx.
		-it is a travesty this hasn’t been massaged into the entire list of ports. 

to have nodejs14/18/gdb/etc all on an “old” 10.7 install really speaks to ethos of this package manager and, at one time, this operating system.

nice job man.

Thanks,
Gagan
