ok I did it w/o using the md5 figure (should have known that)
just wget the 1.4.0 file and 777 it then install/configure as needed.
seems to have worked fine.
Yeah just know that ./build update will probably overwrite that file with the other version. I wonder what the reason directadmin is not using 1.4 yet.
yup this has been working well, thank you for the help.
now need to get all sites working off different port, looks like that will be tons of editing nginx.conf for each domain.
putting varnish onto port 80.
I actually tried that and the issue I had was it also overwrites and nginx customizations like rewrites or added location blocks.
but I didn't dig to far into it, at that point I just started looking at the files individually.
have not had much chance to mess with it though. setting up vps to practice this (varnish-nginx) portion first.
