I am confused by why there is a difference as well. All I do with that
directive is call Py_SetPythonHome() in Python API. The code being:
void
Py_SetPythonHome(char *home)
{
default_home = home;
}
char *
Py_GetPythonHome(void)
{
char *home = default_home;
if (home == NULL && !Py_IgnoreEnvironmentFlag)
home = Py_GETENV("PYTHONHOME");
return home;
}
When Python initialises itself it calls Py_GetPythonHome() at one
point and so what I set should just take precedence over environment
variable. So if value the same, should be fine.
The other thing to keep an eye out on is what is in the PATH
environment variable. By rights it shouldn't matter because if
Py_GetPythonHome() returns a value that should be used. If it isn't,
then Python searches PATH for 'python' executable and uses the
directory above that as PYTHONHOME.
So, that you had to manually set RPATH in mod_wsgi.so shouldn't matter
unless for some reason you have forced it to use wrong Python shared
library.
