I suspect that pykde4's build system is adding false dependencies to pykde4. I also suspect that building it with -Wl,--as-needed in the LDFLAGS enables portage to automatically detect and correct this. Reproducible: Always Steps to Reproduce: 0. You might need -Wl,--as-needed in your LDFLAGS 1. emerge -1v =pyqt4-4.4.4 2. Look at the output from portage. Actual Results: * Messages for package kde-base/pykde4-4.4.4: * Deleting byte-compiled Python modules needlessly generated by build system: * /var/tmp/portage/kde-base/pykde4-4.4.4/image/usr/lib64/python2.6/site-packages/PyQt4/uic/pykdeuic4.pyc * /var/tmp/portage/kde-base/pykde4-4.4.4/image/usr/lib64/python2.6/site-packages/PyQt4/uic/widget-plugins/kde4.pyc * /var/tmp/portage/kde-base/pykde4-4.4.4/image/usr/lib64/python2.6/site-packages/PyKDE4/pykdeconfig.pyc * /var/tmp/portage/kde-base/pykde4-4.4.4/image/usr/lib64/python2.6/site-packages/PyKDE4/__init__.pyc Expected Results: There should have been no messages about byte-compiled Python modules needlessly being generated by the build system. #

Hello Richard, the byte compilation aka optimization should happen in pkg_postinst and should be disabled in src_* phases. typically by modding the build system. Please attach the full full build.log and i'll assign it to the maintainer. Thanks, Michael
Created attachment 234357 [details] build.log from "ebuild $(equery which =pykde4-4.4.4) install" Thankyou for the quick response. Here is the build.log file.
(In reply to comment #2) > build.log from "ebuild $(equery which =pykde4-4.4.4) install" fyi: `FEATURE="keeptemp" emerge -av1 pykde4`

Yes, python modules are byte-compiled by buildsystem. No, they are not installed - they are explicitly removed, only to be byte-compiled later in pkg_postinst. equery files pykde4 | grep '\.pyc' (empty) In other words - no such issue.
