arb fails to run when X11 is not installed

[mmiletto@…]

I installed the latest ARB version (6.0.2) on OS 10.10.2. Running the latest version of MacPorts (2.3.3) and Xcode (6.2).

When I try to run ARB I get the following message: "/opt/local/bin/arb: line 94: ARBHOME: unbound variable" and the program does not launch.

I wonder what I did wrong... Any help would be greatly appreciated!

Thank you

Update: I typed arb_macsetup to set ARBHOME and add ARB to my PATH. Now ARB terminates abnormally...

It looks like you might not have the necessary X window application installed because you are getting the "Can't open display: :0" error.

Install Xquartz found here:

​http://xquartz.macosforge.org/landing/

Then try to run arb.

THANK YOU!!! It works perfectly...

Alternately, you could install the xorg-server port; it provides the same software as manually installing Xquartz (just installed to a different location).
