differnces in guile initialization procedures?

[ctest]

i'm trying to run guile-gtk, and when i run it from a script (using the -s 
option) everything runs ok.  however, when i load it interactively, it 
hangs.  so i get:


bash-2.03$ guile-gtk
gtk> (+ 2 2)

*guile waits forever*



so, i'm thinking there must be a differnce in what gets loaded during 
initialization when it's a script, vs when it's interactive.  Anyone know 
what the differnces are?
