This subject has been covered before. Check the thread "dang .xinitrc"
in the archives. I put ". $HOME/.profile" in my .xinitrc file for
XDarwin, but that does not take care of the Applications menu in Apple
X11. There have been suggestions to modify the X11.app startup script
and also enabling the loginShell for XTerm resources, all of which work
but have their caveats (for example, xterm -ls -e "some command"
wouldn't work if "some command" relied on something in .bash_login or
.profile or .bash_profile; I've never found out why.)
The issue is that if you are used to logging in to a Unix-style system,
login takes care of it for you. However Apple does not use login, and
.xinitrc covers the applications started in .xinitrc and quartz-wm, but
apparently does not cover the menu bar Applications.
Here's a sample of the X11 processes on a NetBSD machine:
USER PID PPID PGID SESS JOBC STAT TT TIME COMMAND
tor 26834 1 26834 8af200 0 Is+ E0 0:00.10 -bash
tor 26856 26834 26834 8af200 0 I+ E0 0:00.01 xinit
tor 26860 26856 26860 8af200 1 I E0 0:00.01 sh
/home/tor/.xinitrc
tor 26881 26860 26860 8af200 1 I E0 0:00.37 gnome-session
As you can see, all the X processes on this machine eventually trace
their way back to the -bash process, which is a login shell. Thus all
the child process inherit the environment. Linux machines behave in
the same way.
In contrast, here is Apple's X11:
PID PPID COMMAND
173 1 /System/Library/CoreServices/WindowServer -daemon
540 173 /Applications/X11.app/Contents/MacOS/X11 -psn_0_1703937
541 540 /Applications/X11.app/Contents/MacOS/X11 --xquartz-be-xinit
-noreset -nolisten tcp -psn_0_1703937
543 1 sh /Users/tor/.xinitrc
565 543 /usr/X11R6/bin/quartz-wm
Note that .xinitrc is started directly from the init process (PID 1)
and does not trace it's ancestry back to a login shell. Additionally I
am guessing the Menu bar Applications menu is started from one of
either process 540 or 541, which again traces it's way back to init and
not a login shell. Thus to adequately cover the bases for inheriting
the environment, I suspect (I haven't tried this) one needs to both
modify the X11.app start-up script as well as source .profile in
.xinitrc.

Thanks for this and the other responses. I use .Xdefaults for other
programs but it didn't occur to me to try to set the resource for
xterm. I can't remember ever having to set xterm for login before.
That works.
I was going to say that this behavior seems like a bug, i.e. that at
some point, I'd assume that you would have "logged in" and the script
would be executed. Since the login on Mac OS X is not shell-based,
that assumption is wrong (and for the vast majority of Mac OS X
users, a behavior they probably don't want or need). I think it would
be nice for the X11 application to assume that it is taking care of
the "login" step, albeit without any kind of authentication.
Anyway, for the record, I did a quick survey of Unix or Unix-like
environments asking the question "Does it execute .bash_profile at
'login'?":
Cygwin terminal: Yes
Cygwin/XFree86(double-clicking startxwin.bat icon)/xterm: No
Cygwin/XFree86(manually executing startx)/xterm: Yes (inherits
current env variables)
xdm/KTerm or xdm/xterm (Red Hat 7.1/x86): Yes
Unix login (Linux, BSD, whatever): Yes
XDarwin (w/or w/o OroborOSX): Yes
X11 for Mac OS X Beta: No
It's subtle, I think I'm being pedantic, but I would like that last
line to say "Yes."
