Over at
gllabs.org is a list of themes and download links that are compatible with GL v1.4.1 (unfortunately, I did not see IvyLeague on the list.

) Perhaps you could try your hand at updating the theme yourself. Here is a
Theme Guide and a
How to Port a Theme tutorial that should be helpful.
You can also checkout more themes in a new visual gallery/chooser/downloader for GL called
vThemes. Also, I've released several new theme ports that you can check out
here.
Hopefully one of these solutions will fit your need.
Thx!
