Version 0.8.1 was released last year. The README says: Release notes for PStreams 0.8.1 ================================ The change in version 0.8.0 that caused the child process to be put in a new process group could prevent the child from exiting when the parent process was killed by a signal. In version 0.8.1 it is still possible to create a new process group for the child, but that must be explicitly requested by setting the pstreams::newpg flag in the pmode argument used to create the new process. Release notes for PStreams 0.8.0 ================================ The child process will now switch to a new process group, with the process group ID the same as the PID. The basic_pstreambuf::killpg() member function has been added to send a signal to the child's process group. New constructors to simplify the common case where the string specifying the file to be executed is the same as the first element of the argv_type vector. Fixes for compatibility with Clang++ and _FORTIFY_SOURCE. Renaming the ebuild to pstreams-0.8.1.ebuild yields a successful build. However, I did not make any thorough checks.
