Daniel, Fabrice,

This is hard (for me anyway). I wasted some time looking
into various things and it is still not obvious to me how
to proceed...

Running scons from the top level results in very upset scons
(https://jira.lsstcorp.org/browse/DM-522). I have nicely
installed xrootd and all other packages qserv depends on,
and I'd like to reuse all that, but it is not obvious to
me which variables should be set to what. e.g. XROOTD_DIR...
is it for include? lib?

I am familiar with custom.py, I have it from past (working)
built, but where should I put it now? In top level qserv?

I don't want each of us to go through these pains one by one.

Can you two possibly document things and provide instructions
how to get the latest qserv build smoothly?

Thanks
Jacek
