Hello Qserv Team - I'm trying to debug some code changes but keeping running into a problem when I try to re-build qserv. I initially build my instance of qserv on lsst-dev03 following the procedure described on Trac: https://dev.lsstcorp.org/trac/wiki/db/Qserv/InstallAuto After running scons, I am able to run qserv-testdata.py and obtain what appear to be reasonable results. However, after making minor changes to the source and running scons a subsequent time within %QSERV_SRC_DIR%, it fails. Here are the contents of the INSTALL-yyyy-mm-dd:hh:mm.log file: lsst-dev03.slac.stanford.edu Using virtualenv-1.7. -- Running: /usr/bin/python virtualenv.py /u1/bchick/sandbox2/qserv-master5 in /u1/bchick/sandbox2/qserv-master5/build/virtualenv-1.7 ERROR : /usr/bin/python virtualenv.py /u1/bchick/sandbox2/qserv-master5 exits with error code (256) at /u1/bchick/src/qserv-master5/admin/qserv-install line 589.

Has anyone else encountered this? Is there a better way to re-build qserv after changing python or c source code? Thanks in advance, Bill P.S.
