David, do you perhaps have the Fink "source /sw/bin/init.sh" startup
command in your ~/.bashrc script? This non-standard placement would
explain that you get the Fink PATH components when you run "screen
$SHELL", because then you would get them in any shell, regardless of
the environment it runs in.
The most common problem I've had with PATH getting clobbered has
involved
system profile/startup scripts clobbering PATH, and the shell
happening to
trigger this.
Look also at /usr/libexec/path_helper.
Thanks for guessing, but none of these explains the behavior I am
seeing. The path_helper script would additionally place /usr/local/
bin and /usr/X11/bin on the PATH, which I am not getting.
I also put tracers in all the shell startup scripts, and I see that
the only ones that are executed are /etc/csh.cshrc and ~/.tcshrc (I
have tcsh as login shell). In none of these scripts there is
anything influencing PATH. I am setting my PATH in scripts run from /
etc/csh.login. I even created a new account with bash as login
shell, and I am seeing the exact same behavior; this time it is only
~/.bashrc that is executed.
It is definitely /usr/bin/screen that is clobbering PATH.
I can't believe I am the only one seeing this. I have seen this on
every machine running Leopard I have looked at and on every account
I have created or could get my fingers on.
I don't have a solution to the problem, but at least a few words of
comfort telling you that I'm also experiencing the exact same problem:
Tiger's screen, OK; MacPorts' screen, OK; Leopard's screen, no PATH. I
have to supply the full path to whatever program I want to run under
Leopard's screen, otherwise I get not found errors.
Lastly, I've not looked through the problem as extensively as you
have, but my setup is rather straight forward with some settings in /
etc/profile and some in ~/.profile, pretty standard situation (no
path_helper(8) tweaking anything). I don't see what could be hampering
screen's environment in my shell configuration, so I'm also guessing
it must be a problem with screen itself.
Regards,...
