Problem with omitting CVSROOT

[Daniel Jaenecke]

Hi!

I have some trouble working with my remote repository. I use pserver 
with ssh tunnel which works in general, but please take a look:

[note: localhost:12401 is tunneled to 2401 on remote machine]

$ export CVSROOT=:pserver:address@hidden:12401/var/cvs/

$ cvs login
Logging in to :pserver:address@hidden:12401/var/cvs/
CVS password:

$ cvs co anymodule
cvs server: Updating anymodule
[...]

$ cd anymodule

$ cvs log
/var/cvs: no such repository

$ cvs -d $CVSROOT log
[desired output]

$ cat CVS/Root
:pserver:address@hidden:12401/var/cvs/



Okay, explicitly adding -d $CVSROOT makes things work, but that's not a 
satisfying solution.
I would be very thankful for any suggestion/help,

regards
