 I have more than one MacPorts prefix. I had cdrtools installed in one of
 them. cdrtools has an mtree violation where it installs things in /etc, as
 already reported in #23035. Having forgotten this, I installed cdrtools in
 another MacPorts prefix on the same machine. The result was:

 {{{
 --->  Fetching cdrtools
 --->  Verifying checksum(s) for cdrtools
 --->  Extracting cdrtools
 --->  Configuring cdrtools
 --->  Building cdrtools
 --->  Staging cdrtools into destroot
 Warning: violation by /etc
 Warning: cdrtools violates the layout of the ports-filesystems!
 Warning: Please fix or indicate this misbehavior (if it is intended), it
 will be an error in future releases!
 --->  Installing cdrtools @3.00_0
 --->  Activating cdrtools @3.00_0
 Error: Target org.macports.activate returned: could not create new link
 "/etc/default/cdrecord": that path already exists
 Log for cdrtools is at:
 /opt/local/var/macports/logs/_Users_rschmidt_macports_dports_sysutils_cdrtools/main.log
 Error: Status 1 encountered during processing.

 }}}

 Following this, /etc had been deleted. The log contains:

 {{{
 :msg:activate --->  Activating cdrtools @3.00_0

 :debug:activate activating directory: /etc
 :debug:activate activating directory: /etc/default

 :error:activate Target org.macports.activate returned: could not create

 }}}

 Fortunately /etc on Mac OS X is just a symlink and could be recreated with

 {{{
 $ sudo ln -s private/etc /etc
 sudo: can't stat /etc/sudoers: No such file or directory
 Segmentation fault
 $ su
 # ln -s private/etc /etc
 # exit
 $
 }}}

 but MacPorts should not be deleting /etc...

 This was using the 1.9 branch @68818
