dev-python/whoosh-2.7.4 with the doc USE flag fails to build if dev-python/sphinxcontrib-websupport is not installed. Reproducible: Always Steps to Reproduce: emerge dev-python/whoosh-2.7.4 with doc enabled without python/sphinxcontrib-websupport installed in the system Actual Results: dev-python/whoosh fails to build. The error indicates that sphinxcontrib-websupport was not found: ``` * python3_4: running distutils-r1_run_phase python_compile_all Traceback (most recent call last): File "/usr/lib/python-exec/python3.4/sphinx-build", line 6, in <module> from pkg_resources import load_entry_point File "/usr/lib64/python3.4/site-packages/pkg_resources/__init__.py", line 3030, in <module> @_call_aside File "/usr/lib64/python3.4/site-packages/pkg_resources/__init__.py", line 3014, in _call_aside f(*args, **kwargs) File "/usr/lib64/python3.4/site-packages/pkg_resources/__init__.py", line 3043, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib64/python3.4/site-packages/pkg_resources/__init__.py", line 654, in _build_master ws.require(__requires__) File "/usr/lib64/python3.4/site-packages/pkg_resources/__init__.py", line 968, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib64/python3.4/site-packages/pkg_resources/__init__.py", line 854, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'sphinxcontrib-websupport' distribution was not found and is required by Sphinx * ERROR: dev-python/whoosh-2.7.4::gentoo failed (compile phase): * (no error message) * * Call stack: * ebuild.sh, line 115: Called src_compile * environment, line 2674: Called distutils-r1_src_compile * environment, line 796: Called _distutils-r1_run_common_phase 'python_compile_all' * environment, line 287: Called multibuild_foreach_variant 'distutils-r1_run_phase' 'python_compile_all' * environment, line 1507: Called _multibuild_run 'distutils-r1_run_phase' 'python_compile_all' * environment, line 1505: Called distutils-r1_run_phase 'python_compile_all' * environment, line 784: Called python_compile_all * environment, line 1794: Called die * The specific snippet of code: * sphinx-build -b html -c docs/source/ docs/source/ docs/source/build/html || die; * * If you need support, post the output of `emerge --info '=dev-python/whoosh-2.7.4::gentoo'`, * the complete build log and the output of `emerge -pqv '=dev-python/whoosh-2.7.4::gentoo'`. * The complete build log is located at '/var/tmp/portage/dev-python/whoosh-2.7.4/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/dev-python/whoosh-2.7.4/temp/environment'. * Working directory: '/var/tmp/portage/dev-python/whoosh-2.7.4/work/Whoosh-2.7.4' * S: '/var/tmp/portage/dev-python/whoosh-2.7.4/work/Whoosh-2.7.4' >>> Failed to emerge dev-python/whoosh-2.7.4, Log file: ``` Expected Results: dev-python/whoosh should pull python/sphinxcontrib-websupport when the doc USE flag is enabled. python/sphinxcontrib-websupport should probably be added as a compile dependency to dev-python/whoosh when the "doc" USE flag is enabled. Notice that this will generate a circular dependency between dev-python/sphinxcontrib-websupport and dev-python/whoosh due to the following: - dev-python/sphinxcontrib-websupport depends on dev-python/whoosh - dev-python/whoosh with doc depends on dev-python/sphinxcontrib-websupport The circular dependency is easily broken by emerging dev-python/whoosh without doc, emerging dev-python/sphinxcontrib-websupport and finally re-emerging dev-python/whoosh with doc. These kinds of circular dependencies happen in other packages when the "doc" USE flag is enabled, and can be also broken by first installing the packages without the "doc" USE flag.
This is probably a missing dependency in dev-python/sphinx itself.
