I would like to build unity-lens-music on my newly-upgraded Ubuntu 12.10 machine. I followed these instructions from the unity website to get the code. The README was empty but I guessed that ./autogen.sh would be a sensible place to start. Unfortunately it exits with the following error: checking for LENS_DAEMON... no configure: error: Package requirements (glib-2.0 >= 2.27 gobject-2.0 >= 2.27 gio-2.0 >= 2.27 gio-unix-2.0 >= 2.27 dee-1.0 >= 1.0.7 sqlite3 >= 3.7.7 gee-1.0 json-glib-1.0 unity >= 6.90.0 unity-extras >= 6.90.0 tdb >= 1.2.6) were not met: No package 'dee-1.0' found No package 'sqlite3' found No package 'gee-1.0' found No package 'json-glib-1.0' found No package 'unity' found No package 'unity-extras' found No package 'tdb' found When I attempt to satisfy the dependencies that aren't found using apt-get install I either find that there is no exact match (e.g. 'dee-1.0' which matches several packages), I already have the latest version (e.g. sqlite3, unity) or there is no match at all (e.g. unity-extras and tdb). There is a later suggestion to modify PKG_CONFIG_PATH if I have installed software in a non-standard location but, to my knowledge, I have not. How should I proceed?
