Can anyone direct me to some information about what WITHOUT_PROFILE="YES" actually means.

if I remember right, from information about src.conf, I believe that

WITHOUT_PROFILE
WITHOUT_PROFILE=
WITHOUT_PROFILE=true
WITHOUT_PROFILE="YES"
...

are all functionally equivalent as it does ignore the rest, though I 
could be wrong and this could be my problem.  I do know for sure that 
the WIHTOUT_BIND, WITHOUT_NTP, are working correctly as they are gone 
form the system, prior to me installing the versions from ports after 
the build/install world.

Yes this does apply only to system. With the above options buildworld / 
buildkernel / install kernel / install world/ mergemaster / reinstall 
all ports, I have my problem.  Remove all options, repeat no problem.  
Remove just WITHOUT_PROFILE repeat again, problem is back.  So I was 
wrong as to that line being the cause, at least by itself.

I did a lot of initial testing with port option changes, and changes to 
make.conf on my system, thought maybe it was clang, etc.  Didn't get 
anywhere, the system is running on a ZFS boot partition, and as a last 
effort I tried on UFS.  It worked, but I also realized I forgot the 
src.conf settings.  I copied my ZFS systems boot environment and rebuilt 
without src.conf, it now works as well.

Currently doing a fresh install on ZFS to build from ground up with the 
same process used originally, except without the src.conf and confirm I 
can repeat its success.  Then I can do some more testing with adding 
options back into the src.conf to try and narrow down which of those 
options is causing the problem.  If I can figure out which one, or 
combination of them is the cause, then I will hopefully have something 
that can lead to someone with more knowledge than I have being able to 
discover why its having the problem.

The port doesn't fail to compile it installs fine, and 99.5% of it runs 
perfect, just one little thing that I need to work hangs up for about 5 
minutes, before timing out, but doesn't log an error, even with insanely 
verbose debugging, it acts as if it completed but it didn't.

I posted another message about the specific problem several days ago, 
before I had it figured out to be caused somehow by something in the 
src.conf file.  I am trying to run Squid (version 3.2.6 is the current 
port) in reverse proxy, the problem is only when doing a post via HTTPS 
above a certain size, somewhere between 2k and 3.2k is where it begins.
