x11-libs/wxGTK-2.8.8.1 attempts to install the files
/usr/share/bakefile/presets/wx.bkl
/usr/share/bakefile/presets/wx_unix.bkl
/usr/share/bakefile/presets/wx_win32.bkl
which are created by eselect wxwidgets as symlinks to their versioned
equivalents.
This appears to be caused by the following difference between
wxGTK-2.8.4-collision.patch and wxGTK-2.8.8-collision.patch:
$(INSTALL_DIR) $(DESTDIR)$(datadir)/bakefile/presets
-- (cd $(srcdir)/build/bakefiles/wxpresets/presets/ ; $(INSTALL_DATA)
wx.bkl wx_unix.bkl wx_win32.bkl $(DESTDIR)$(datadir)/bakefile/presets)
+ (cd $(srcdir)/build/bakefiles/wxpresets/presets ; $(INSTALL_DATA)
wx.bkl wx_unix.bkl wx_win32.bkl $(DESTDIR)$(datadir)/bakefile/presets)
+ (cd $(srcdir)/build/bakefiles/wxpresets/presets/ ; for i in wx.bkl
wx_unix.bkl wx_win32.bkl; \
+ do $(INSTALL_DATA) $$i
$(DESTDIR)$(datadir)/bakefile/presets/wx$(WX_RELEASE_NODOT)$${i##wx} ; done)
$(INSTALL_DIR) $(DESTDIR)$(libdir)/wx/include/$(TOOLCHAIN_FULLNAME)/wx
Notice that the removal of the installation of the unversioned files has itself
been removed from the newer patch, presumably inadvertently when updating it to
account for the missing trailing slash.
