看来 FreeBSD ports 树正忙着从 pkg-config 过渡到 pkgconf。http://www.mail-archive.com/[电子邮件受保护]/msg00018.html
我首先认为，作为最终用户，这不会影响我，并且像 portmaster 这样的工具会处理任何转换。然而今天，常规portmaster -a给出了以下问题：
sudo portmaster -a
===>>> Gathering distinfo list for installed ports
===>>> Starting check of installed ports for available updates
===>>> The devel/pkg-config port moved to devel/pkgconf
===>>> Reason: pkg-config has been replace by pkgconf
===>>> Launching child to reinstall pkg-config-0.25_1
===>>> All >> pkg-config-0.25_1 (1/1)
===>>> The devel/pkg-config port moved to devel/pkgconf
===>>> Reason: pkg-config has been replace by pkgconf
===>>> Port directory: /usr/ports/devel/pkgconf
===>>> Launching 'make checksum' for devel/pkgconf in background
===> No options to configure
===>>> Gathering dependency list for devel/pkgconf from ports
===>>> No dependencies for devel/pkgconf
===>>> Returning to update check of installed ports
===>>> All >> (1)
===>>> The following actions will be taken if you choose to proceed:
Install devel/pkgconf
===>>> Proceed? y/n [y]
Finishing with:
Stop in /usr/ports/devel/pkgconf.
===>>> Installation of pkgconf-0.8.4 (devel/pkgconf) failed
===>>> Aborting update
===>>> Update for devel/pkgconf failed
===>>> Aborting update
Terminated
===>>> You can restart from the point of failure with this command line:
portmaster <flags> devel/pkgconf
FreeBSD 的“普通”用户应该做什么？我无法删除 pkg-config，因为很多端口依赖于它。如何解决这个问题？
答案1
/usr/ports/UPDATING在进行端口升级之前，您应该始终阅读。在这种情况下，它有关于弃用的说法pkg-config：
20120726:
AFFECTS: users of devel/pkg-config
AUTHOR: [email protected]
devel/pkg-config has been replaced by devel/pkgconf
# portmaster -o devel/pkgconf devel/pkg-config
or
# portupgrade -fo devel/pkgconf pkg-config-\*
pkgng:
# pkg set -o devel/pkg-config:devel/pkgconf
# pkg install -f devel/pkgconf
如果您按照这些说明进行操作，您选择的端口管理工具（似乎适合portmaster您的情况）将删除pkg-config并安装pkgconf，并将更新下面的包注册表数据库/var/db/pkg以反映更改。如果您是portupgrade用户，升级还将修复portupgrade自己的数据库中的依赖关系图，该数据库与标准注册表是分开的。
未来的安装/升级应该“正常工作”。

对于那些没有 ports-mgmt 工具的人来说，这应该有效：
pkg_delete -f pkg-config\*
