I'm trying to compile music-applet-2.5.1 and am receiving some errors.

I have extracted the tarball and after running "sudo ./configure" I get this

checking for pygtk-2.0... Package pygtk-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `pygtk-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'pygtk-2.0' found
configure: error: Library requirements (pygtk-2.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.


I have installed the package pygtk2 from the repos. I have used nautilus to run a search on the whole file system for pygtk-2.0.pc and nothing came up.

If I have the right packages installed, just in a strange location, how can I find where they are? and what command will tell pkg-config about it?

Otherwise, what other packages do I need to install?

The .pc files are located in /usr/lib/pkgconfig and they are used by pkg-config to identify the installed version of a software, e.g:
in my system returns 2.12.1

In this case you can use the env. variable PKG_CONFIG_PATH to change the search path of .pc files:
Your package manager should be able to resolve dependencies and d/l all the needed software. Afaik pygtk depends on pygobject.

The reguired package is 'pygtk2-devel' which provides
/usr/lib/pkgconfig/pygtk-2.0.pc and all other files
needed for compiling with pygtk2.

When "configure" asks for <package> it always means
<package-devel>.
