That is a good policy in general - I have to agree.

Options that spring to mind:

1) Find another way to determine all the subnets across all interfaces.
I have gone through the ifconfig source code - it isn't pretty.
The netlink API was designed for this class of use. Any attempt to avoid 
using the netlink API will result in re-implementing chunks of the 
netlink API.

2) Define these dependencies as "absolutely necessary".
Problem solved by definition :-)

3) Define these dependencies as optional - used if present and generate 
a helpful warning if not present.
For people compiling for themselves it doesn't matter much (unless they 
have a HDHomeRun and they have multiple IP addresses, in which case they 
should install the libraries).
For people building public packages the libraries should be used so that 
it will work for everyone using the packages.

Any thoughts/preference or any other options that spring to mind?
