>Description:
There are several path issues that make using the dhcp
4.1.1 version of dhclient difficult to use.
Since the port does not set the configure prefix the path,
_PATH_DHCLIENT_SCRIPT gets set to /sbin/dhclient-script
instead of /usr/local/sbin/dhclient-script.
Another configure prefix problem is that the path installed
in dhclient-script's run-time environment (CLIENT_PATH),
is set to "/sbin". But since this string is used an an
execve() environment vector element and is missing the
leading "PATH=" (probably a bug with dhcp 4.1.1) the
dhclient-script ends up with the default path of
"/usr/bin:/bin". Either way this means common programs
used by the dhclient-script script are not on the path.
>How-To-Repeat:
Run dhclient and notice that although the package installs
/usr/local/sbin/dhclient-script it invokes /sbin/dhclient-script
and that the script emits errors such as "route: not found" (see
attachment lose1.txt).
>Fix:
Run configure with the correct --prefix and set the the
dhclient script and config paths. Also, set CLIENT_PATH to
include /sbin and /usr/sbin (and add missing "PATH="); see
attached patches.
