os.system() calls system() (in Modules/posixmodule.c).  How any given
libc implements system() is a vendor issue, but it doesn't surprise me
that it would use execvp().

Without the exact error message, as other replies have also requested,
we're no wiser.

I also don't comprehend your assertion about there being a known issue of
Python not using the system's execvp().  If your gripe is that Lib/os.py
implements os.execvp() in terms of execv()/execve(), then information
about why you believe that is a problem would also be appreciated.
