Yes that seems to have done it! Now..a final complication...I'm still
using Winter2013 v6_2.  We use scipy.  I've installed anaconda 1.8.0
which includes scipy 0.13.0 and numpy 1.7.1.  I was thinking to install
scipy 0.13.0 via:
eups distrib install --nolocks scipy 0.13.0+1
However, when I do that..there is a dependency on numpy 1.8.0

Required product tcltk 8.5.12+1 is already installed; use --force to
reinstall
Required product sqlite 3.7.14+1 is already installed; use --force to
reinstall
Required product python system is already installed; use --force to
reinstall
Installing numpy 1.8.0+1 for generic...
Cannot guess version without .git directory or git.version file; version
will be set to "unknown"
Setting up environment (via ./eupssetups.sh)...

Any suggestions?  I guess I could install numpy 1.8.0 and update the
installed scipy within anaconda.  Maybe I should get DMstack to use
numpy 1.8.0, though maybe I need to do a fresh installation so that
things are set  up correctly?

Take care,
Heather
