Good catch, checked in and uncommented -- the FEA socket manager is 
using it.

I would consider this a teething problem with SCons and should be looked 
at before 1.7-RC is cut; the current scheme is not desirable (/opt/sfw 
doesn't exist in a number of places, for example).

There are a number of link line items which could do with being pushed 
down to individual areas of the tree. Even with Autotools, we've tended 
to skip this, as just having the library in the ld.so depends is  cheap 
even if none of the functions get called (and thus no PLT entries 
resolved at runtime).

One of the things that isn't in, for example, is using the linker 
$ORIGIN facility, although SCons has hooks for dealing with this. For 
example, it's not always possible to run binaries directly w/o 
installing them or setting LD_RUN_PATH/LD_LIBRARY_PATH in the environment.

I've made a lot of progress on Thrift this week, and it looks like we 
can cut over to it from XRL without mass refactoring of the protocols, 
so I'll try to look at the HAVE_IPV6_MULTICAST issue next week, if Ben 
has a crack first, even better.

cheers,
