Ok, so it looks like this prefix is to support a different install  
location on remote nodes. Unfortunately, PTP 1.1 does not support  
this. I'll add it to the PTP 2.0 TODO list. As a work around, have you  
tried setting PATH and LD_LIBRARY_PATH and then running mpiexec  
without --path?

Here are a couple of things to try:

1. It looks like you're using PTP 1.1.0. There is a bug fix release  
(1.1.1) available from http://www.eclipse.org/ptp/downloads.php. I  
would recommend installing it just in case.

2. Click on the PTP preferences (from the main Eclipse preferences).  
Make sure the control and monitoring system choices are set to Open  
Runtime Environment (ORTE). Open the PTP preferences and click on Open  
RTE. Make sure the ORTE proxy service file path is /clhome/EVANS/ 
eclipsePlugins/eclipse/plugins/org.eclipse.ptp.linux.x86_64_1.1.0/bin/ 
ptp_orte_proxy. If you need to change any of these, quit out of  
Eclipse and restart.

If you still have problems, please send me all the console output again.
