I was trying to install a program, but it wouldn't compile. The program was runewin - an oldish and dead-since-2010 program - and the error was this:I had no idea what that meant, so I googled. Just when my googler was about to fall off, I found an article that said compiling 'pygtk' from source was a workaround for the issue, but in the end the matter was resolved. I don't know what they did to fix it though. So, I decided to go and compile pygtk from source. Now, it gives me its own error, saying:Code:Traceback (most recent call last): File "/usr/local/bin/runewin", line 54, in <module> gtk.window_set_default_icon_from_file("/usr/share/pixmaps/runewin.svg") glib.GError: Couldn't recognize the image file format for file '/usr/share/pixmaps/runewin.svg'Now I'm stuck and I have no idea what to do. Is there any hope for me?Code:configure: error: Package requirements (pygobject-2.0 >= 2.21.3) were not met: No package 'pygobject-2.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables PYGOBJECT_CFLAGS and PYGOBJECT_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
