Package: x2goclient Version: X2Go Client v. 4.0.5.2 (Qt - 4.8.7) Operating System: OS X El Capitan version 10.11.6 Tags: macos osx x2goclient xmodmap path I have installed the latest x2goclient package on OS X El Capitan using MacPorts. I have also installed the MacPorts xorg-server and xmodmap packages. In my user account .profile script, MacPorts has added the following line to set the PATH variable: export PATH="/opt/local/bin:/opt/local/sbin:$PATH" I have confirmed that xmodmap exists in one of these directories, in: /opt/local/bin When attempting to connect to any X2Go session, an error dialog appears with the following message before the application crashes: xmodmap failed to start. This likely means the binary is not available. The current search path is: /usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin X2Go Client will now terminate. It appears that /opt/local/bin is not being searched for xmodmap, despite its presence in the PATH variable of my user account .profile script. I even attempted to reboot before starting x2goclient in case the PATH variable needed to be re-read, but the error did not change. This is preventing me from using the OS X x2goclient application.
