On x86 (and probably all platforms, though I haven't tried it elsewhere) fop-0.93-r1 fails to build unless xmlgraphics-commons-1.1 has been built with the jpeg use flag. Without the use flag, certain TIFF classes are missing from the xmlgraphics-commons jar file. By default, 'jpeg' is not set. I'm building fop on a very bare-bones headless system, so pretty much all packages are built with minimal default options. Reproducible: Always Steps to Reproduce: 1.USE="-jpeg" emerge xmlgraphics-commons 2.emerge fop 3.Fails!
Added a built_with_use check to pkg_setup in dev-java/fop.
