"IUSE" is "Inherited USE". The "bug", if you want to call it that, is that I start my USE variable with "-*", which overrides default settings. The bugfix is to make app-text/poppler[xpdf-headers] mandatory for the apvlv ebuild. In that case, the ebuild will halt with an error message stating that app-text/poppler[xpdf-headers] is needed. This beats the ebuild compile dying with a message about missing files. -- Walter Dnes <waltd...@waltdnes.org>
