"me too" The change from 1.7.7 to 1.7.9 ebuild is that PYTHON_DEPS is now included in DEPEND. I don't really get it if subversion could live without python in 1.7.7, why does it need in 1.7.9.
Just tested, it works correctly without python, the ebuild needs only a few modifications: 1) Remove the PYTHON_DEPS line from DEPEND (line 47). COMMON_DEPEND already has that with the python USE flag (which should control the dependency anyway). 2) The python_export_best line (line 187) and the ac_cv_python_includes line (line 192) needs a conditional (i'm not sure if the second one is needed, as ruby lacks the conditional too, and i don't have ruby isntalled), eg: if use python; then python_export_best fi [...] if use python; then ac_cv_python_includes='-I$(PYTHON_INCLUDEDIR)' fi ac_cv_path_RUBY="${EPREFIX}"/usr/bin/ruby18 ac_cv_path_RDOC="${EPREFIX}"/usr/bin/rdoc18 \ econf --libdir="${EPREFIX}/usr/$(get_libdir)" \ [...] This should nail it.
Created attachment 349810 [details, diff] proposed fix I've prepared Zoltán Halassy's suggestions in comment 3 as a patch. After applying the patch, subversion successfully builds on my machine with USE="-python" PYTHON_TARGETS="python3_2".
Just checked the patch from attachment 349810 [details, diff] with USE="python" PYTHON_TARGETS=python2_7 and it works fine too.
fixed: 20 Jul 2013; Michał Górny <mgorny@gentoo.org> subversion-1.7.9.ebuild: Lower the build-time requirement of Python to Python bindings or USE=test. Add REQUIRED_USE for Python.
