Hi there, I'm trying to build a new package for despotify[1], which includes python and ruby bindings for the library "libdespotify", as well as a couple of console clients. The difficulty is that the python and ruby bindings are not build by the main Makefile, and though they do provide their own, these assume that libdespotify and its pkg-config file are already installed on the system. I've managed to patch the build system so that it all works fine when I build it with dpkg-buildpackage on my Ubuntu precise box, but when using a Debian unstable chroot, I get behaviour that I don't understand: I have produced a modified pkg-config file that tells the build systems to look in the package build directories for the built library and header files, and this causes the correct "-L" and "-I" and "-l" options to be passed to gcc. However, on running `pbuilder', `dpkg-buildpackage', or even just `make' in the python binding directory, the build fails:

Finally, some (fairly obvious) information: "/tmp/buildd/despotify-0.1\~svn520/debian/../lib/.libs" is where libdespotify is built and found before it is installed. Can anyone shed any light on this problem?
