ruby-runner
* template/ruby-runner.c.in: wrapper to set dynamic loading path
environment variable. /bin/sh on Mac OS X 10.11 (El Capitan)
clears DYLD_LIBRARY_PATH.
it must:
- do nothing even if current directory is not present
- do not set other environment variables, e.g. PWD, SHLVL, etc
- do not open other FDs, e.g. pipes for timer thread
