[winswitch] XPRA_SOCKET_DIR=~/.xpra: Command not found

[Bob Tennent]

I'm trying to upgrade from xpra-0.3.2 to xpra-0.5.3 on Centos-6.3. When
I do

xpra --ssh="ssh -p2202" attach ssh:remotehost:100

(which worked before) I get

  XPRA_SOCKET_DIR=~/.xpra: Command not found.

Why?

This is the output from xpra info on the remote system:
