When xdm runs your .xsession it doesn't source your .cshrc or .login
files. You can set the path explicitly as you normally could for any SH
script; or you can place all environment-setting statements in a separate file
and source it from both the .xsession file and your shell configuration file;
or, if you set your PATH in your .cshrc file, the normal place, you can make
your .xsession have PATH set simply by making it a csh script, i.e. by starting
your .xsession file off with "#!/bin/csh".
	If this doesn't work, also try starting off with:
	#!/bin/sh # Reset path:  PATH=`csh -c 'echo $PATH'` ; export PATH
