Interestingly enough the sslxmlrpc_server.py EOF error was resolved in 
the same way as the GUI error.  I can generate a patch file if 
necessary, but essentially it is a 1 line fix in 2 files.  Change 
"import popen2" to "import subprocess" in emulabclient.py and 
emulabserver.py.

This is probably the case anywhere that popen2 is used.  The default 
version of Python in FreeBSD7.2 has depreciated popen2 anyway.
