I am pretty sure that one of the catalogs I have enabled has the 2.0 version of libhildonmm. I don't know how to tell which one it is. I would disable it and install theremin.

It seems to me that the right thing to do is to correct your deb so that it specifies the correct version (instead of specifying a versionless dependency.) That way, when the libhildonmm package gets updated to version 2.0 in the catalogs you're using, you won't have to change anything. Application manager will still pull down the 1.0 version specified in your deb.

I tried to search for the exact steps you should take; but I was unsuccessful. I didn't know what the maemo auto-builder is. It's a service that runs on maemo.org and builds your package when you want to push to the extras repo? Well, i couldn't find any information on how to add a specific dependency.

How does autobuilder know what libraries your program depends on? There's got to be a way give it a specific version.
