Subject: pyepcis does not seem to honor EPICS_CA_ADDR_LIST

Hi,

I have encountered a problem with pyepics, the most recent version on rhel7. 

The trouble is: I have many PV on a local IOC, but also want to access another PV reachable 
via a gateway on port 5062. 

I set an appropriate EPICS_CA_ADDR_LIST like: export EPICS_CA_ADDR_LIST="hipa-cagw:5062:localhost“,
and this works to my satisfaction with the standard caget from EPICS base. 

If I start python from the same terminal == same environment, load pyepics, and try to use
caget() I cannot access any PV’s at all. I have not found any reference to EPICS_CA_ADDR_LIST in the
pyepics docs. Is this a limitation or a bug? Or am I missing something?

We eventually worked around the problem by installing a calc record pointing to the PV accessible through 
the gateway in our IOC and this works.   

Best Regards,

    Mark Koennecke
