Hi Karan, Mats,

In our site catalog we have

<profile namespace="env" key="PATH">/cvmfs/oasis.opensciencegrid.org/osg/modules/gcc/4.9.3/bin:/cvmfs/oasis.opensciencegrid.org/osg/modules/python-2.7.7/bin:/cvmfs/oasis.opensciencegrid.org/osg/modules/lua/bin:/cvmfs/oasis.opensciencegrid.org/osg-software/osg-wn-client/3.2/current/el6-x86_64/usr/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin</profile>

In particular, we need the version of gfal-copy that lives in /cvmfs/oasis.opensciencegrid.org/osg-software/osg-wn-client/3.2/current/el6-x86_64/usr/bin. However in a recent run

<https://sugar-dev2.phy.syr.edu/pegasus/u/lppekows/r/69/w/2/j/628/ji/194>

at sites that have gfal-copy in /usr/bin the transfer is using it:

PilotID: Name = "glidein_11953_727322296@hansen-a050.rcac.purdue.edu”

AttributeError: 'Gfal2Context' object has no attribute ‘set_user_agent'

I see that at line 430 pegasus-transfer does

1. figure out the full path to the executable
   full_path = backticks("which " + executable + " 2>/dev/null”)

So I don’t see why it isn’t finding the preferred version, unless the PATH somehow isn’t getting picked up properly. Is that possible?

Thanks,
