I'm not sure whether I understand this fully, especially `masking'=20 leftover empty directories? Empty directories are normally removed by doing @unexec rmdir %D/libdata/pkgconfig 2>/dev/null || true in pkg-plist, which is not more difficult than having USE_GNOME=3D pkgconfig in the ports Makefile. I guess we should have an auto-prune in=20 pkg-deinstall, I'll see if I can cook something up. >>>> OTOH you seem to selectively ignore the other samples given, which=20= >>>> does >>>> not seem very wise to me either.

I guess you will not get many people to agree to this. Besides, since they currently don't (and there are more of them) you have to=20 build-depend applications linking with those on pkg-config anyway. > I stated my technical opinion before, I can repeat it again: > > In this case library installs important metadata as a .pc file, and > configure scripts of other applications read these .pc files to obtain > the metadata, unable to configure for the library without them. The > reading of .pc file is done using external program, pkg-config. Some applications need pkg-config to extract the information from the .pc file, others just link with the library without pkg-config. It is not necessary to link with the library, it is necessary for some applications to configure them during build time. > Here comes a heated debate, if library should provide all possible > applications with a pkg-config, via it's runtime dependency, or if = every > possible application should build depends on pkg-config. > > I believe that library should provide everything needed for other > applications to be able to link the library. > > I believe that library should run depends on pkg-config. FreeBSD Porter's Handbook, 5.7 Dependencies <http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters- handbook/makefile-depend.html>: 5.7.2 RUN_DEPENDS This variable specifies executables or files this port depends on=20 during run-time. 5.7.3 BUILD_DEPENDS This variable specifies executables or files this port requires to=20 build. That is why I believe that a port should require all tools it requires=20= to build in BUILD_DEPENDS, while stuff that is not needed to run the port should=20= not be in RUN_DEPENDS. And i do not need pkg-config to run xmllint or=20 applications linking with libxml, so they should build-depend on pkg-config, not run-depend. What references do you have to support your opinion? -Oliver
