That was a great hint.
I tried the following.

$ GPG_TTY=$(tty) gpg -d myfile.gpg

and it popped up a graphical window asking for my passphrase. Typed in 
the phrase, entered and it decripted the file.

So, this is good and/or bad, depending on how one looks at it. What I 
*would* prefer is that on a tty it not ask me the passphrase via a 
graphical pop up and just ask me on std in.

What happens is that when I logout from my KDE session, reboot (probably 
to 'kill' gpg agen) and then login via a *virtual tty* and try to 
decrpyt the same file using gpg, gpg errors out by complaining that 
there is no secret key (this is with the GPG_TTY exported as you 
suggested). Next, when I login to my KDE session, try the same gpg 
command from a terminal, it pops up the passphrase window, which accepts 
my passphrase and decrypt the file succesfully.

So, how do I tell gpg to work on std in when on a terminal instead of 
relying on a graphical session?

Thanks.
