I'm setting up a new system and ran into a failure in the doxygen build while it was looking for QT, which isn't installed yet. I checked the ebuild and QT is listed as a runtime dependancy instead of a dependancy. If it's needed by the configure scripts it is both runtime and compiletime so this should be chanage. details: >>> emerge (7 of 38) app-doc/doxygen-1.3.9.1 to / >>> Downloading http://ebiz-randd.cti-pet.com/mirrors/gentoo/distfiles/doxygen-1.3.9.1.src.tar.gz --06:50:25-- http://ebiz-randd.cti-pet.com/mirrors/gentoo/distfiles/doxygen-1.3.9.1.src.tar.gz => `/usr/portage/distfiles/doxygen-1.3.9.1.src.tar.gz' Resolving ebiz-randd.cti-pet.com... 10.80.254.2 Connecting to ebiz-randd.cti-pet.com[10.80.254.2]:80... connected.

Reproducible: Always Steps to Reproduce: 1. Attempt to emerge something on a new system which requires doxygen and qt both, while QT is not already installed. 2. Wait ;-) 3. This can be fixed pretty easily by making qt a depend instead of an rdepend in the doxygen ebuild.
Well, I take it back, in the ebuild I see this: RDEPEND="media-gfx/graphviz qt? ( x11-libs/qt ) doc? ( tetex? ( virtual/tetex ) virtual/ghostscript )" DEPEND=">=sys-apps/sed-4 ${RDEPEND}" So why isn't QT a depend? Anyhow, I ran emerge -pv doxygen and QT was listed before it properly, but when I run emerge -uDpv doxygen QT is listed after doxygen. Sounds like this may be a portage bug not a doxygen bug.
Taking this a bit further, I removed the doc use flag and noticed that it fixed the DEPEND/RDEPEND problem. No doubt it's a cyclic dependancy now. I don't really know how to fix this. I would think it should be possible to do this, but it may require something close to a bootstrap-like process of building binaries first then going back and rebuilding documentation. It might actually be nice to add some type of non-linear processing to portage where an ebuild acts more like a single task instead of a many sequential tasks.
I also ran into this same problem with the same work around. In my case, I'm rebuilding a system where I lost the root drive. After completing stage3 and running 'emerge -puDv system', I copied the make.conf file from an identically configured machine which includes USE="doc". In this example, executing 'emerge -puDv kde' with all of my preferred USE flags set brings in nearly all my standard desktop packages. I had to execute 'USE="-doc" emerge qt' in order to be able to subsequently emerge doxygen.
I experimented with trying to workaround this, but I can't see a way to get the current portage to resolve this correctly. If anyone has any suggestions, feel free to reopen this bug.
