After apt-get install beagle, I try to launch best (the beagle GUI) and it gives this error message: Unhandled Exception: System.DllNotFoundException: libgeckoglue.so in (wrapper managed-to-native) Beagle.Util.GeckoUtils:blam_gecko_utils_init_services ()in <0x00007> Beagle.Util.GeckoUtils:Init () in <0x0006c> Best.Best:Main (System.String[] args) I have the library upgraded to the newest version, however: $ sudo apt-get install libgecko2.0-cil Reading package lists... Done Building dependency tree... Done libgecko2.0-cil is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. After Googling, it seems that libgeckoglue.so depends on a deprecated file which may cause a problem: <a href="http://www.ubuntuforums.org/archive/index.php/t-94246.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.ubuntuforums.org/archive/index.php/t-94246.html </a> How do I get around this?
