[MapServer]Variables not read when building python mapscript

[nsavard@…]

Variables on line two of "mapscriptvars" file not read when building python
mapscript.  This causes some problem when using non standard library location. 
I included the "mapscriptvars" file and error message when starting the building
process.

The command use is "python setup.py build".

Good to see Python being used at DM Solutions!  Write me for help any time. 

Frank Warmerdam fixed this in the CVS main (4.3), but it's not going to be
fixed in 4.2.  Too close to the release.  We'll take of it for 4.2.1.

Work around is to run the setup script like

   python setup.py -I -I/opt/gdal_12/include build

See http://docs.python.org/dist/dist.html for more info about Python's
distutils module.

My idea for the best solution is to have the Python setup ignore mapscriptvars.
Instead, the mapserver makefile will write a distutils setup.cfg file in
mapscript/python.  Then we can clean up and simply setup.py.

I tried the workaround and obtain an error message (see below).

I forgot to say that I'm switching to 4.3 for testing purpose.

[sgillies@…]

Sorry, my previous instructions were bad.  Try

   python setup.py build_ext -I /opt/gdal_12/include build

I'm happy to use mapscript Pyton.  Thank you for your help.

This is fixed in 4.2 as well as 4.3.  I simply copied the setup.py
in 4.3 (fixed by Frank) to the 4.2 branch and verified that it works.
