[Scons-users] OSX Library link names include undesired prefix

[Bill Deegan]

Generally the SConscript would be located in the directory with the source
and the variant dir wouldn't be the top level direcotry.

In essence in your example the current dir is variant dir'd to build.
This can lead to some nastiness where on subsequent builds the variant dir
build can get replicated in the build dir.

I'll try to take a look at this later today.
For sure the _RPATH which is what creates the rpath constructs on the
command line is not propagating properly (at least on OSX)
