#<two-way stream 00f0db68>

This has been fixed in CVS today. I sent previously a email explaining the problems, but LTK has to be changed. The line that executes RUN-PROGRAM should now read similar to the SBCL one, because ECL implements the :WAIT argument

#+:ecl(ext:run-program program args :input :stream :output :stream :error :output :wait wt)

Great, we'll change that in the next release.
