Yes, by hand but also using ports/pkgsrc systems. That is a packager 
builds a package and the results and experience is based on what was 
installed on that developer's system. Another user of the port 
specification has a different environment which may result in a 
different build.

Some pkgsrc buildlink specifications have things like:

BUILDLINK_FILES.subversion-base+= bin/svn-config

BUILDLINK_FILES.libnet10+=               bin/libnet10-config       bin/wish*

So packages that depend on these have these symlinks in its build PATH 
before the system's possible versions of the same.

As far as I see, FreeBSD ports does not install the rc.d scripts nor 
configuration files to any examples directory.  Maybe on a case-per-case 
basis and I am just overlooking it?  (I do see some FreeBSD ports do 
install foo.default or foo.sample configurations right in the 
/usr/local/etc/ but as far as I know this is not consistent and 
certainly could be messy over time and with many packages.)

For pkgsrc, it is the default procedure fo any configuration file is 
installed to an examples directory. This is nice so you can easily 
compare any time. At deinstall time, it can compare and remove installed 
configurations that have not changed. And on new install, configurations 
may be different so new version is only into examples directory and a 
message tells you about this.  This is consistent across all software in 
pkgsrc installing configurations.

$ ls -l /usr/pkg/share/examples/wget/ /usr/pkg/etc/wgetrc  
-rw-r--r--  1 root  wheel  4224 Aug 26  2008 /usr/pkg/etc/wgetrc

total 12
-r--r--r--  1 root  wheel  4224 Aug 26  2008 wgetrc

I can easily tell pkgsrc builds to use /etc if I choose.
