Just a gentle hint.  This list is for development discussion.  Your 
question would have been more appropriate on the general user list, or 
even on the portage-specific devel list, where at least it wouldn't have 
bothered all these devs, most of which work on packages other than 
portage, and who I'm sure we'd both rather have spending their time fixing 
bugs or doing package bumps than reading what could quickly become an 
overwhelming number of questions here, if such user questions weren't 
steered elsewhere. =:^(

But you've asked it here now, so might as well answer it while I'm 
steering you elsewhere for next time.  =:^)

One possibility, assuming you're using standard rsync for your portage 
tree (not the webrsync or similar options) is to assign something like:

PORTAGE_RSYNC_EXTRA_OPTS="--exclude-from='/etc/portage/rsync.exclude'"

then read the rsync(1) manpage and add something appropriate to the named 
file (maybe start with /profiles/license_groups/yourfilename, but really, 
see the manpage, as there's a reason that doesn't start with 
/usr/portage).  See the make.conf(5) manpage for the description of the 
PORTAGE_RSYNC_EXTRA_OPTIONS setting.

Here, I have several non-default files and subdirs in PORTDIR (including 
my layman managed overlays, in the perfectly logical to me 
$PORTDIR/layman/ ), that I keep from being synced using that method.  That 
works just fine for my purposes, so I expect it will work for yours as 
well. =:^)

More directly, the portage(5) manpage says that any files found in /etc/
portage/profile/ should override files found in the tree profiles, where 
necessary.  I'd expect it to work for license_groups just as I know it 
works for other files, and believe it would be a bug if it didn't.  
However, if for whatever reason it does /not/ work, I know the 
rsync.exclude functionality works as I depend on it every time I sync. =:^)
