Library seems not to be known to pkg-config. pkg-config --list-all | grep flickrnet returns nothing. configure-script of a program, which needs the flickrnet library, fails with message: flickrnet not found. Reproducible: Always Steps to Reproduce: 1. Download f-spot sources 2. unzip 3. execute ./configure Actual Results: Configure fails with message: flickrnet not found Expected Results: Succeed in configuring the sources
flickrnet-bin does not provide a pkg-config .pc file, so it's not the ebuild's fault. Take a look at how the f-spot ebuild gets around this: --with-flickrnet=/usr/$(get_libdir)/mono/FlickrNet/FlickrNet.dll You'll need to do the same thing when compiling f-spot by hand. Does that solve your problem?
