[kepler-dev] Problems with pipes, R actors

[Latronico Elizabeth (RTC1)]

Hello Kepler developers,

I am new to Kepler and I am getting strange errors about pipe problems
when trying to run the demos with R actors in them.  For example, in
/demos/00-StatisticalSummary.xml I get the following error.  I
downloaded both the binary and also source code for version
kepler-1.0.0beta3 and I have the same problem with both.  I get similar
error messages for the other demos with R actors.

Has anyone seen a similar problem?  I checked the newsgroup archives but
didn't find any related information.

Thanks for your help!
Beth
