Can we also add a switch that enables building individual modules "outside" 
the source tree the way it was prior to GNU-Radio 3.0.2?

This will allow building packages as individual modules. The pkgsrc framework 
keeps track of the dependencies and enables users to pick and choose modules 
for installation pulling in dependencies as required. The pkgsrc modules are 
currently patched to facilitate this behaviour. The pkgsrc sources and the 
corresponding patches can be found on:

http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/ham/

I've made mentioning of this many times before but sofare haven't received a 
reponse nor seen any action. Just let me know if there is any hope to see 
this implemented.
