Geez man...
Here I thought you were using maemo gregale extras
SDK isn't the proper catalog for your purposes

Yeah...well...there are a good half dozen catalogs you could have used instead...excluding maemo gregale extras
Hm....
It would be easy to find under gronmayer's it maemo site....for example..

Just navigate there ...click on the 770 device (os 2006) tab to the right...
Then type osso-xterm in the search box...
And you should get about a half dozen catalogs that contain xterm.
Careful though...
Some catalogs there state they are online ...when they are in fact ...not.
So check catalogs first...

Fact is ...check my signature and you will find a thread called "the Lost Gronmayer Catalogs" ...
I did an extensive study of functioning catalogs and lost catalogs recoverable and non recoverable ...and how to utilize the Gronmayer meta catalog optimally...
