I should clarify that I know I can just put the dranges sources in, e.g, 
a 'dranges' subdirectory, compile drange/*.d into a library and do 
something like:

dmd -Ldranges/dranges.a -Idranges test.d

...and I could modify /etc/dmd.conf by hand to add my dranges directory 
to the appropriate paths. But I wonder if I'm missing a more idiomatic 
way to install third-party libraries for D2.

Thanks,
Graham
