I like it, AFAIK pkg-config is always in most distros, so this new 
requirement shouldn't be a problem. Moreover, this provides us a way to 
easily maintain the library version dependencies. Since this also 
affects other libraries, I'll wait for Harald's ACK before commiting 
this to conntrack and libnetfilter_conntrack.

cheers,
