Despite exporting the library path, it's still not working for me :-( It keeps telling me the "segmentation failure" error mentioned before. Do I have to install libpango and the other packages? If so, what it's the command to accomplish that? I tried it via dpkg already, it told me something with "permission denied" (aegis). Any help is appreciated!

Edit: It tells me that /opt/mozbuildhm/libxpcom.so is missing. I checked the tar-archive if this file simply hasn't been extracted, but this file isn't there even in the tar-archive! I don't get that...
