 all works this compiles the .pyc version while we know we have write
 access to the dir. If we wait until after install and let it happen at
 runtime, it is likely that the user won't have write permissions to the
 dir and it will have to be recompiled in memory every time the user uses
 the lib.

 If you just want to compile the python_grass![67].py file, why not run a
 minimal script which simply imports that file, i.e.:
 {{{
 #!/usr/bin/env python
 import python_grass7
 }}}
 This won't require a dummy session.

 generalize the $ARCH.

 You can specify the directories with:
 {{{
 python setup.py build --build-lib build/lib.foo --build-temp
 build/temp.foo
 }}}

 Or you can calculate the directories which it will use as:
 {{{
 plat_specifier = ".%s-%s" % (distutils.util.get_platform(),
 sys.version[0:3])
 lib_dir = os.path.join('build', 'lib' + plat_specifier)
 temp_dir = os.path.join('build', 'temp' + plat_specifier)
 }}}
