$ ./emerge -p mozilla

These are the packages that I would merge, in order:

[enabled] java crypt gtk2 ssl gnome
[disabled] ipv6

  I personally think you forgot to include the emergehelp-module.  :-)

x200 bin # emerge --pretend mozilla
Traceback (most recent call last):
  File "/usr/bin/emerge", line 6, in ?
    import os,sys,portage,emergehelp,xpak,string,re,commands,time,threading,shutil,traceback

Well, you can't patch /usr/bin/emerge, you have to patch the source (in
/var/tmp...) and merge it with ebuild.

  ah.  right.  that helped.  rather nifty, but some linewrapping
  should be done for the USE flags:

[enabled] java crypt ssl ldap gnome 
[disabled] 
[unset] ipv6 gtk2 mozsvg mozcalendar mozaccess mozinterfaceinfo
        mozp3p mozxmlterm moznoirc moznomail moznocompose moznoxft 

  of course, wrapping at the window width is a good thing.  :-)

  anyhow, way cool and very nifty!  thanks!

You did patch the source in /var/tmp... (and not /usr/bin/emerge) against
portage 2.0.46-r4?
